The rich chem. of solution-processable red and near-IR organic emitters has emerged as an attractive and progressive research field because of their particular applications in organic optoelectronics and bioimaging. Three PMI-based fluorophores were synthesized via conjoining anthracene and donor moieties (-Ph, -N,N-PhNMe2) with a PMI core via an acetylene linkage at the peri-position, which helped to attain extensive electronic conjugation, which was reflected in red and NIR-emission in solution The key mol. features to be highlighted here are: all three dyes are strongly emissive in solution, as unveiled by the excellent absolute fluorescence QYs; and they possess tuneable emission properties, guided by the donor strength and a profound Stokes shift. The three fluorescent dyes demonstrated appreciable singlet-oxygen (1O2) sensitivity when photoirradiated with methylene blue (MB) in solution, showing a substantial blue-shift in emission in a ratiometric manner. Further, the treatment of dye-MB solution with alpha-tocopherol (1O2 scavenger) validated the presence of 1O2 as the only oxidizing species generated by MB in solution Computational investigations gave insight into the twisting of donor moieties in their ground-state optimized geometries, the modulation of the FMO energy gap, and the thermodn. feasibility of the 1O2 reaction. Finally, via taking advantage of the red and NIR-emission, we successfully utilized one of the fluorophores as a lipid-droplet marker for bioimaging in HepG2 cells.

Mechanochromic luminophors with strong solid-state emission are promising candidates for high-contrast mechanochromic luminescence materials. Meanwhile, mech. responsive luminogenic mols. with tricolor switching are highly desirable but are seldom reported. In this work, three anthracene-based donor-acceptor-π-donor (D-A-π-D) type benzothiadiazole derivatives were designed and synthesized. These luminogens showed remarkable aggregation-induced emission (AIE) or aggregation-induced emission enhancement (AIEE) effect. Furthermore, these luminogens exhibited bright and different solid state fluorescence involving yellow-green, yellow and orange colors, and the fluorescence of their solids could be effectively regulated by mech. grinding. For luminogen I, its solid displayed reversible two-color mechanofluorochromic property. As for luminogens II and III, their solids displayed fluorescent colors change from yellow to yellow-green upon slight grinding, and the yellow-green light-emitting solids were converted into orange fluorescent solids after heavy grinding, demonstrating interesting three-color mechanofluorochromism features.9,10-Dibromoanthracene(cas: 523-27-3Product Details of 523-27-3) was used in this study.

The hybridized local and charge transfer (HLCT) excited state is a successful strategy to produce both high external and internal quantum efficiencies. Based on the HLCT scheme, two isomeric donor-acceptor (D-A)-type excited-state intramol. proton transfer (ESIPT) chromophores of o-hydroxyphenyl phenanthroimidazole (HPI)-based emissive mols. (mTAHPI and pTAHPI) and their OH-protected derivatives (pTAPI) were designed and explored for organic light-emitting diodes (OLEDs). The photophys. study and d. functional theory (DFT) calculations revealed that all mols. possessed the HLCT excited-state characters without exhibiting ESIPT photophys. properties, whereas the NMR spectroscopy, single-crystal and phys. property analyses discovered the existence of strong intramol. H bonds and intermol. interactions in both mTAHPI and pTAHPI. Consequently, their OLEDs displayed blue emissions with a narrow full width at half maximum (65-68 nm) and achieved excellent electroluminescence (EL) performance with a low turn-on voltage of 2.8 V. Particularly, pTAHPI-based devices showed the highest maximum external quantum effciency (EQE) of 8.13% with an ultra-high brightness of 18 100 cd m-2. The maximum singlet exciton utilization efficiency (ηs) of the device was estimated to be as high as 94%, which is among the best results of blue electroluminescence to our knowledge.

We report two donor-acceptor (D-A) materials based on a cyanoanthracene acceptor paired with diphenylamine (DPAAnCN) and carbazole (CzAnCN) donor moieties. These compounds show hybrid locally excited (LE) charge-transfer (CT) excited states (HLCT), which we demonstrated through a combined photophys. and computational study. Vacuum-deposited organic light emitting diodes ( OLEDs ) using these HLCT emitters exhibit maximum external quantum efficiencies (EQEmax) close to 6%, with impressive exciton utilization efficiency (Φs) of >50%, far exceeding the spin statistic limit of 25%. We rule out triplet-triplet annihilation and thermally activated delayed fluorescence as triplet harvesting mechanisms along with horizontal orientation of emitters to enhance light outcoupling and, instead, propose a “”hot exciton”” channel involving the nearly isoenergetic T2 and S1 states.

Electric Literature of C14H8Br2In 2022 ,《Harnessing near-infrared light via S0 to T1 sensitizer excitation in a molecular photon upconversion solar cell》 was published in Journal of Materials Chemistry C: Materials for Optical and Electronic Devices. The article was written by Beery, Drake; Arcidiacono, Ashley; Wheeler, Jonathan P.; Chen, Jiaqi; Hanson, Kenneth. The article contains the following contents:

Integrating mol. photon upconversion via triplet-triplet annihilation (TTA-UC) directly into a solar cell offers a means of harnessing sub-bandgap, near IR (NIR) photons and surpassing the Shockley-Queisser limit. However, all integrated TTA-UC solar cells to date only harness visible light. Here, we incorporate an osmium polypyridal complex (Os) as the triplet sensitizer in a metal ion linked multilayer photoanode that is capable of harnessing NIR light via S0 to T1* excitation, triple energy transfer to a phosphonated bis(9,10-diphenylethynyl)anthracene annihilator (A), TTA-UC, and electron injection into TiO2 from the upcoverted state. The TiO2-A-Zn-Os devices have five-fold higher photocurrent (∼3.5 μA cm-2) than the sum of their parts. IPCE data and excitation intensity dependent measurements indicate that the NIR photons are harvested through a TTA-UC mechanism. Transient absorption spectroscopy is used to show that the low photocurrent, as compared to visible light harnessing TTA-UC solar cells, can be atributed to: (1) slow sensitizer to annihilator triplet energy transfer, (2) a low injection yield for the annihilator, and (3) fast back energy transfer from the upconverted state to the sensitizer. Regardless, these results serve as a proof-of-concept that NIR photons can be harnessed via an S0 to T1* sensitizer excited, integrated TTA-UC solar cell and that further improvements can readily be made by remedying the performance limiting processes noted above.

Chen, Xinyu; Zhang, Tong; Han, Yanning; Chen, Qiao; Li, Chengpeng; Xue, Pengchong published an article in 2021. The article was titled 《Multi-responsive fluorescent switches and iodine capture of porous hydrogen-bonded self-assemblies》, and you may find the article in Journal of Materials Chemistry C: Materials for Optical and Electronic Devices.Electric Literature of C14H8Br2 The information in the text is summarized as follows:

A four-armed divinylanthracene derivative was designed and synthesized to construct multifunctional porous self-assemblies. It could form stable supramol. gels, and its fluorescence gradually increased during gelation, exhibiting aggregation-induced emission enhancement. SEM, TEM, BET and mol. simulation suggested that gelators stacked to form one-dimensional porous nanoribbons by multiple hydrogen bonds. The xerogel film might change the fluorescence from green to yellow under force stimuli because of the enhanced π-stacking and recover its fluorescence after solvent annealing. Moreover, fluorescent films acting as sensing materials were applied in the quant. detection of gaseous nitrobenzene and the detection limit reached 1.5 ppb. The sensing film was not sensitive to the gases of common organic solvents. More interestingly, the solids composed of porous nanoribbons might efficiently capture iodine in aqueous and gaseous states, and could be recycled many times.

《Dual mode selective detection and differentiation of TNT from other nitroaromatic compounds》 was written by Goudappagouda; Dongre, Sangram D.; Das, Tamal; Santhosh Babu, Sukumaran. Reference of 9,10-Dibromoanthracene And the article was included in Journal of Materials Chemistry A: Materials for Energy and Sustainability in 2020. The article conveys some information:

Selective detection of explosives, especially TNT, is a highly desirable area of research and various explosives detection devices including fluorescent sensors are already in place. However, multi-mode sensors will be more useful and reliable than conventional fluorescent “”Turn Off”” sensors. One of the challenges is the development of selective sensors to prevent illegal transport of commonly used explosive TNT through on-the-spot anal. In this context, a fluorescent polymer-based selective detection is reported of TNT using both fluorometric and colorimetric signals. In addition, colorimetric differentiation of TNT from other nitroarom. compounds is made possible by complexing with various amines. Even though many other sensors are available for TNT, the current demonstration is unique in terms of selectivity, sensitivity, reliability, portability, and rapidity of results. The as-developed explosive detection kit can be useful in both civilian and military operations to trace the illegal transport of TNT as well as for post-explosion anal.

Carmen; Chakraborty, Pradip; Real, Jose Antonio. Reference of 9,10-Dibromoanthracene And the article was included in Journal of Materials Chemistry C: Materials for Optical and Electronic Devices in 2020. The article conveys some information:

The research of new multifunctional materials, as those undergoing spin crossover (SCO) and luminescent properties, is extremely important in the development of further optical and electronic switching devices. As a new step towards this ambitious aim, the coupling of SCO and fluorescence is presented here following two main strategies: whether the fluorescent agent is integrated as a part of the main structure of a 3D SCO coordination polymer {FeII(bpan)[MI(CN)2]2} (bpan = bis(4-pyridyl)anthracene, MI = Ag (FebpanAg), Au (FebpanAu)) or is a guest mol. inserted within the cavities of the 3D switchable framework {FeII(bpb)[MI(CN)2]2}·pyrene (bpb = bis(4-pyridyl)butadiyne, MI = Ag (FebpbAg·Pyr), Au (FebpbAu·Pyr)). The magnetic, calorimetric, structural, UV-visible absorption and fluorescent characterizations were performed confirming the occurrence of a SCO-fluorescence interplay in the studied compounds Moreover, the relevance of the intrinsic or extrinsic nature of the luminescence on the efficiency of the interplay is discussed on the basis of the available information.
