Inspired by secologanin’s highly congested functional groups, a secologanin-based diversity-oriented synthesis (DOS) strategy for novel pseudo-natural alkaloids was developed. All the reactive units of secologanin were involved in these operation simplicity protocols under mild reaction conditions, including the one-step enantioselective transformation of exocyclic C8, C8/C11 and C8/C9/C10 as well as the chemoenzymic manipulation of endocyclic C2/C6 via the attack by various nucleophiles. A combinatory scenario of the aforementioned reactions further provided diverse polycyclic products with multiple chiral centers. Preliminary activity screening of these newly constructed mols. led to the discovery of antimalarial and highly potent neuroprotective skeletons. The application of green biorenewable secologanin in diversity-oriented pseudo-natural monoterpenoid alkaloid synthesis might encourage the pursuit of valuable bioactive frameworks.

Zhang, Xiao;Li, Jiao-Yang;Zhang, Kai;Ding, Lei;Wang, Chuan-Kui;Fung, Man-Keung;Fan, Jian research published 《 Highly efficient thermally activated delayed fluorescence emitters with suppressed energy loss and a fast reverse intersystem crossing process》, the research content is summarized as follows. Thermally activated delayed fluorescence (TADF) emitters with low non-radiative decay and a fast reverse intersystem crossing (RISC) process are highly desirable for achieving efficient organic light-emitting diodes (OLEDs). This work revealed the excited-state structural relaxation induced emission behavior of the frequently used donor unit, spiro[acridine-9,9′-fluorene] (spAc). This structural change at the excited state from bent conformation to planar conformation was suppressed greatly by doping the emitter in a solid matrix, thus avoiding the non-radiative energy loss and enhancing the utilization of excitons. Furthermore, the spAc-based emitters achieved small ΔE(¹CT-³CT) and ΔE(³LE-³CT) with the aid of the robust configuration design, thus promoting a fast RISC process up to 1.69 x 10⁶ s^-1. As a result, these TADFs demonstrated excellent photoluminescence quantum yields (PLQYs) in the range of 91.0-98.2%. OLEDs based on BPCN-spAc showed a state-of-the-art efficiency with an external quantum efficiency (EQE) of nearly 30% and power efficiency (PE) over 80 lm W^-1 at 592 nm. This study deepened the understanding of the luminescent behavior of robust TADF emitters in solution and in the solid state, which could provide helpful guidance for the design of efficient TADF materials.

Yu, Hanbo;Song, Xiaoxian;Xie, Ning;Wang, Jiaxuan;Li, Chenglong;Wang, Yue research published 《 Reversible Crystal-to-Crystal Phase Transitions with High-Contrast Luminescent Alterations for a Thermally Activated Delayed Fluorescence Emitter》, the research content is summarized as follows. Merging thermally activated delayed fluorescence (TADF) and mechanochromic luminescence (MCL) into one single mol. is a promising strategy for developing multifunctional organic materials. Herein, a unique multifunctional mol. TPA-DQP, comprising a large π-conjugated diquinoxalino[2,3-a:2′,3′-c]phenazine (DQP) as the acceptor and triphenylamine (TPA) as the donor, is designed and synthesized. TPA-DQP possesses polymorphism, efficient TADF emission as well as MCL property with high-contrast in emission colors from 576 to 706 nm. Reversible crystal-to-crystal phase transitions in response to external stimuli such as vapor fuming and heating are realized on the basis of the two polymorphs of TPA-DQP. The distinct crystal-to-crystal phase transition is attributed ultimately to the change of packing arrangements and intermol. interactions of the two polymorphs under stimuli. Furthermore, TPA-DQP-based organic light emitting diode (OLED) device achieves external quantum efficiency as high as 18.3% at 676 nm, which represents the best performance for deep-red OLEDs based on MCL-active TADF emitters. This study reports a novel MCL-active TADF material that exhibits crystal-to-crystal phase transition and brings insight into the underlying relationship between mol. packing modes and the photoluminescent behavior.

Yuan, Feng;Liu, Xiaohua;Tan, Lifeng research published 《 Binding properties of ruthenium(II) complexes [Ru(phen)2(7-R-dppz)]²⁺ (R = methyl or bromine) toward poly(U)•poly(A) RNA duplex》, the research content is summarized as follows. Two Ru(II) complexes containing different substituents, [Ru(phen)2(7-CH3-dppz)]2+ (Ru1) and [Ru(phen)2(7-Br-dppz)]2+ (Ru2), have been synthesized in this study. The binding properties of Ru1 and Ru2 with the duplex RNA poly(U)•poly(A) (where “•” denotes the Watson – Crick base pairing) have been researched by biophys. techniques and viscosity measurements. Anal. of spectral titrations and viscosity measurements indicate that Ru1 and Ru2 bind to the duplex via intercalative, and the binding affinity of Ru1 with the duplex is remarkably higher than that of Ru2. Furthermore, fluorescence emission spectra demonstrates that although complexes Ru1 and Ru2 can act as mol. “light switches” for the duplex RNA, alters in fluorescence emission of Ru1 and Ru2 are prominent differences, and the effectiveness of Ru1 is more remarkable compared with that of Ru2. The melting experiments suggest that the duplex RNA stabilizing effects of Ru1 and Ru2 differ from each other, among them, complex Ru1 can obviously enhance the stability of the duplex RNA, while Ru2 has only a slightly stabilizing effect for the duplex RNA, indicating that Ru1 preferentially binds to RNA duplex over Ru2. The obtained results indicate that subtle modifications of the intercalative ligand of Ru(II) polypyridyl complex with either Me or bromide group have a significant effect on the duplex-binding discrimination.

Ye, Zecheng;Chen, Jinzhu research published 《 Sulfonate-Grafted Metal-Organic Frameworks for Reductive Functionalization of CO₂ to Benzimidazoles and N-Formamides》, the research content is summarized as follows. Metal-organic frameworks (MOFs) with inner salt of 3-(pyridinylium)-1-propanesulfonate (PS) as the organic linkage were developed as catalysts (PS/MOFs) for reductive functionalization of carbon dioxide (CO₂) to benzimidazoles and N-formamides. The pendant -SO₃^– anion in the PS/MOFs acted as an organocatalytic active site for reductive cyclization of CO₂ with 1,2-phenylenediamine to afford 1H-benzo[d]imidazole. A linear correlation was observed between the catalytic performance (in terms of turnover frequencies) and the sp. surface area of PS/MOFs at a low conversion level of 1,2-phenylenediamine. The authors’ theor. study revealed significantly reduced energy barriers from 2.03 eV under catalyst-free conditions to 0.97 eV in the presence of the catalyst. The developed PS/MOFs can efficiently promote a broad range of benzimidazoles in 88-99% yields through reductive cyclization. Moreover, the PS/MOFs can readily catalyze N-formylation of various monoamines with CO₂ as the carbonyl source for quant. syntheses of N-formamides. The research thus highlights MOF-based catalysts for organocatalytic transformation of CO₂ into high value-added chems.
