Silyl Rearrangements in Gold‐Catalyzed Transformations
European Journal of Organic Chemistry, EarlyView.The synergy between the exceptional ability of gold catalysts to activate unsaturated substrates and the inherent tendency of organosilicon reagents to undergo silyl‐group rearrangements has unlocked a range of novel transformations, enabling access to otherwise challenging molecular architectures.

FlexMat, EarlyView.A blue‐hazard‐free single‐emissive‐layer white OLED is realized using an anti‐quenching multiple‐resonance TADF emitter, BNCT. By integrating a sterically protected MR core with efficient energy transfer capability, BNCT enables warm‐white emission with high efficiency, negligible hazardous blue photons, and a simplified device architecture for next ...

FlexMat, EarlyView.Two exciplex emitters are constructed based on a host‐guest doping strategy, and their exciton dynamics processes are investigated in depth. High‐performance OLEDs are fabricated by employing these exciplexes as emitters or sensitizers, providing excellent electroluminescence efficiencies and low efficiency roll‐offs.

Quinoxaline Derivatives. XII. The Reactions of Quinoxaline 1,4-Dioxides with Acetic Anhydride [PDF]
Bulletin of the Chemical Society of Japan, 1987 Abstract Quinoxaline 1,4-dioxide (XIIIa) with acetic anhydride gave 1-acetoxy-2(1H)-quinoxalinone (XIVa) which was prone to facile hydrolysis to yield 1-hydroxy-2(1H)-quinoxalinone (XVa). Both XIVa and XVa were isolated from the reaction mixture.

FlexMat, EarlyView.A “gemstone‐necklace” FASCE strategy synthesizes single‐component white polymers (PTF‐Qx) by alternating rigid TADF units with flexible alkyl chains. The non‐doped rigid device achieves a high EQE of 15.66% with stable white emission (CIE: 0.36, 0.46).

Fe3O4 magnetic nanoparticles (MNPs) as an effective catalyst for synthesis of indole derivatives [PDF]
Nanochemistry Research, 2018 The principal aim of this research is the application of Fe3O4 (MNPs) in the synthesis of some indole derivatives. Fe3O4 MNPs were prepared by Co-Precipitation method from the reaction of FeCl2.4H2O and FeCl3.6H2O in ammonia solution.

Modular Donor‐Acceptor Diradicaloids Based on an Electron Deficient N‐Heteroacene Acceptor
Small, EarlyView.This work presents a modular approach to donor‐acceptor‐donor (D‐A‐D) diradicaloids that show systematic evolution of their energy gaps, singlet‐triplet splittings, and diradical character (y). The correlation of (opto)electronic, spin, and magnetic properties with high‐fidelity theoretical investigations provides clear connections between the degree ...
