Guan, Weijiang published the artcileDesign of a Temperature-Independent Luminescent Probe for Visualization of Ice-to-Liquid Transition at -129°C, Safety of 1-Bromooctane, the publication is Journal of Physical Chemistry C (2022), 126(17), 7556-7563, database is CAplus.

The temperature-dependent nature and intense emission in solution of fluorescence mols. prevent them from visualizing various processes accompanying temperature changes (e.g., the liquid-ice transition at ultralow temperatures). To overcome the intrinsic difficulty, we synthesized a custom-designed fluorescent probe to exhibit the temperature-independent negligible fluorescence in the solution state but emit bright light in the icing state. The ice-to-liquid transition of four hydrocarbons, whose f.ps. are between -27 and -129°C, can be sensitively visualized using the proposed temperature-independent fluorescent probe. More interestingly, we have built a homemade platform to enable the real-time imaging of the f.ps. of these four hydrocarbons within 3 min. For the first time, we designed a liquid-ice transition-sensitive probe at ultralow temperatures, different from the conventional temperature-dependent systems. This success will not only help to gain insights into the icing mechanisms but may also contribute to the development of portable visualization devices for monitoring phase transition.

Jing, Liling published the artcileSynthesis and carbene-insertion preparation of hydrophobic natural polymer materials for rapid and efficient oil/water separation, Category: bromides-buliding-blocks, the publication is Applied Surface Science (2022), 152394, database is CAplus.

In response to frequent oil spills and increasing discharges of oily wastewater, a variety of materials and methods have been developed to treat with oil-water mixtures In this paper, a simple and versatile method to modify a broad spectrum of natural polymer surfaces (wood aerogel, pulpboard, filter paper, cotton cloth, electrospinning gelatin film, ultrafine polypropylene fiber) was reported. This modification was based on aryl diazo compounds with hydrophobic functional groups as precursors, which were thermally activated to generate highly active carbene intermediates and induce the X-H (X = O, C,…) insertion reaction on the surface of substrates. The success of surface modification was demonstrated by the irreversible changes of the surface properties and the application on multi-behavior oil/water separation Moreover, according to the Owens-Wendt-Rabel-Kaelble method, the influence of the dispersion force and the polar force on various material surfaces was given to explore the separation mechanism. This one-step modification provides a facile and efficient strategy to achieve renewable, biodegradable, and environmentally friendly materials and surfaces with low surface energy, which offers considerable potential applications on disposal of oil pollution in the environment.

An, Xiang published the artcileUniversal 4-qualifiable fluorene-based building blocks for potential optoelectronic applications, Synthetic Route of 111-83-1, the publication is Chinese Chemical Letters (2022), 33(12), 5137-5141, database is CAplus.

Herein, a universal 4-qualifiable fluorene-based building block I, which is a fundamental mol. segment to functionalize and obtain novel conjugated materials, was demonstrated. Compared to the traditional modification at 9-site, addnl. 4-position functionalization provided an exciting blueprint to not only tune electronic structure and excited state via p-n mol. design engineering and space charge-transfer strategy, but also allow for optimizing intermol. arrangement and obtaining solution-processing ability. The introduction of the 4-site substituent in fluorene based semiconductors may endow materials with unique properties. Finally, two stable deep-blue light-emitting conjugated polymers, PODOPF and PODOF, by utilizing the 4-substituent fluorene based building block were successfully prepared It is believable that the performance, stability and processibility of reported outstanding fluorene-based conjugated mols. can be further optimized based on this universal building block.

Zhou, Shengxi published the artcileEnhancing the Performance of Small-Molecule Organic Solar Cells via Fused-Ring Design, Name: 1-Bromooctane, the publication is ACS Applied Materials & Interfaces (2022), 14(5), 7093-7101, database is CAplus and MEDLINE.

Organic solar cells (OSCs) as the promising green energy technol. have drawn much attention in the last two decades. In comparison to polymer solar cells, small-mol. organic solar cells (SMOSCs) have the advantages of precise chem. structure and mol. weight, purification feasibility, batch reproducibility, etc. Despite of the recent advances in mol. design, the efficiencies of SMOSCs are still lagging behind those of polymer-based OSCs. In this work, a new small-mol. donor (SMD) with a fused-ring-connected bridge denoted F-MD has been designed and synthesized. When F-MD was applied into SMOSCs, the F-MD:N3 blends exhibited a power conversion efficiency (PCE) of over 13%, which is much higher than that of the linear π-bridged mol. L-MD based devices (8.12%). Further studies revealed that the fused-ring design promoted the planarity of the mol. conformation and facilitated charge transport in OSCs. More importantly, this strategy also lowered the crystallinity and self-aggregation of the films, and hence optimized the microstructure and phase separation in the corresponding blends. Thereby, the F-MD-based blends have been evidenced to have better exciton dissociation and reduced charge recombination in comparison with the L-MD counterparts, explaining the enhanced PCEs. Our work demonstrates that the fused-ring π-bridge strategy in small-mol.-donor design is an effective pathway to promote the efficiency of SMOSCs as well as enhance the diversity of SMD materials.

Tian, Yong published the artcileNovel metal complexes of pyridineimine derivative used as auxiliary electron acceptor of D-(A-π-A)₂ motif dye sensitizer: synthesis and photovoltaic application, SDS of cas: 111-83-1, the publication is Journal of Solid State Electrochemistry (2022), 26(3), 719-727, database is CAplus.

The auxiliary acceptors of metal complexes can easily regulate the electron-withdrawing ability of electron acceptor and adjust the balance of push-pull electron of D-A-π-A motif dye sensitizers. Two series of the D-(A-π-A)₂ motif dye sensitizer (BDTT-i.m.-Co, BDTT-i.m.-Cu, BDTT-i.m.-Zn, BDTT-i.m.-Cd and FL-i.m.-Co, FL-i.m.-Cu, FL-i.m.-Zn, FL-i.m.-Cd) which use metal complexes of pyridineimine derivative as auxiliary acceptor were designed, synthesized, and characterized. The photovoltaic test of eight complex-based dye sensitized solar cells (DSSCs) showed that the short-circuit photocurrent d. (J_SC) and the power conversion efficiency (PCE) of two series dye sensitizers are sequentially increased. BDTT-i.m.-Cd have the highest J_SC of 15.58 mA cm^-2 and the PCE of 9.13% under AM 1.5 irradiation, which may be due to that electron-withdrawing ability of the auxiliary acceptor metal complexes of pyridineimine derivative can be changed by the strength of coordination bond of the complexes. They also show good terminal stability with decomposition temperatures (T_d) higher than 300 °C.

Reported the oxidative umpolung of 2,3-disubstituted indoles toward enantioselective dearomative aza-spirocyclization to give the corresponding spiroindolenines using chiral quaternary ammonium hypoiodite catalysis. Mechanistic studies revealed the umpolung reactivity of C3 of indoles by iodination of the indole nitrogen atom. Moreover, the introduction of pyrazole as an electron-withdrawing auxiliary group at C2 suppressed a competitive dissociative racemic pathway and enantioselective spirocyclization proceeded to give not only spiropyrrolidines but also four-membered spiroazetidines that were otherwise difficult to access.

Cain, Caitlin N. published the artcileTile-Based Pairwise Analysis of GC x GC-TOFMS Data to Facilitate Analyte Discovery and Mass Spectrum Purification, Recommanded Product: 1-Bromooctane, the publication is Analytical Chemistry (Washington, DC, United States) (2022), 94(14), 5658-5666, database is CAplus and MEDLINE.

A new tile-based pairwise anal. workflow, termed 1v1 anal., is presented to discover and identify analytes that differentiate two chromatograms collected using comprehensive two-dimensional (2D) gas chromatog. coupled with time-of-flight mass spectrometry (GC x GC-TOFMS). Tile-based 1v1 anal. easily discovered all 18 non-native analytes spiked in diesel fuel within the top 30 hits, outperforming standard pairwise chromatog. analyses. However, eight spiked analytes could not be identified with multivariate curve resolution-alternating least-squares (MCR-ALS) nor parallel factor anal. (PARAFAC) due to background contamination. Analyte identification was achieved with class comparison enabled-mass spectrum purification (CCE-MSP), which obtains a pure analyte spectrum by normalizing the spectra to an interferent mass channel (m/z) identified from 1v1 anal. and subtracting the two spectra. This report also details the development of CCE-MSP assisted MCR-ALS, which removes the identified interferent m/z from the data prior to decomposition In total, 17 out of 18 spiked analytes had a match value (MV) > 800 with both versions of CCE-MSP. For example, MCR-ALS and PARAFAC were unable to decompose the pure spectrum of Me decanoate (MVs < 200) due to its low 2D chromatog. resolution (~0.34) and high interferent-to-analyte signal ratio (~30:1). By leveraging information gained from 1v1 anal., CCE-MSP and CCE-MSP assisted MCR-ALS obtained a pure spectrum with an average MV of 908 and 964, resp. Furthermore, tile-based 1v1 anal. was applied to track moisture damage in cacao beans, where 86 analytes with at least a 2-fold concentration change were discovered between the unmolded and molded samples. This 1v1 anal. workflow is beneficial for studies where multiple replicates are either unavailable or undesirable to save anal. time.

Kabir, Shahriar published the artcileNear-infrared organic photodetectors with a soluble Alkoxy-Phthalocyanine derivative, Formula: C8H17Br, the publication is Optical Materials (Amsterdam, Netherlands) (2022), 112209, database is CAplus.

The condition of the bulk-heterojunction (BHJ) is an important factor for photodetectors as it significantly influences the efficiency of exciton dissociation from bound exciton pairs inside the active layer. In this study, we realized near-IR (NIR) photodetectors with the BHJ system of a soluble donor organic semiconductor, 1,4,8,11,15,18,22,25-octaoctyloxy-phthalocyanine, and phenyl-C61-butyric acid Me ester. By experimenting with the blend ratio of the organic materials, we observed substantial change of device performance owing to the change in the crystalline condition and morphol. of the active layer. Our organic photodiodes with optimized BHJ active layer reached shot noise limited specific detectivity of 2.1 x 10¹² Jones and external quantum efficiency of 18% with a bias of -0.5 V at the NIR wavelength of 770 nm. We attributed this improvement to the decrease in grain size inside the BHJ which resulted in an increased exciton dissociation efficiency at the donor-acceptor interface.
