Hinge‐Like Mechanochromic Mechanophores Based on [2.2]Paracyclophane
Angewandte Chemie, EarlyView.Hinge‐like supramolecular mechanophores utilizing [2.2]paracyclophane have been developed. In the force‐free state, the rigid [2.2]paracyclophane forces two luminophores into proximity, leading to excimer‐dominant photoluminescence. Stretching the polyurethane films into which the mechanophores are covalently incorporated results in the structures of ...

Angewandte Chemie, EarlyView.A robust molecular design strategy for MR‐TADF emitters via heterocyclic carbazole integration to strengthen weak C─N bonds was proposed. Blue MR‐TADF emitters m‐Cz‐DABNA and tBu‐Cz‐DABNA have achieved ultra‐narrow FWHMs (24/21 nm), high PLQYs (88%/95%), and record‐high EQEs (23%/26%).

Asian Journal of Organic Chemistry, EarlyView.Abstract This publication presents the geometries of 157 nitro‐ and polynitropyrazoles. Among these, 109 compounds were theoretically studied using mainly the B3LYP/6–311++G(d,p) level of theory. Three‐parameter Lee‐Yang‐Parr (B3LYP) is a density functional theory (DFT) method widely used in computational chemistry and constitutes an acceptable ...

Angewandte Chemie, EarlyView.At doping ratios ranging from 1 to 12 wt%, the BN‐S and BN‐Se‐based sensitizer‐free OLEDs exhibited nearly unchanged EL spectra with small FWHMs of 27–30 nm and EQEmax of 36.4–43.1%. The BN‐Se‐based OLED exhibited low efficiency roll‐off, with EQEs remaining at 36.7 and 31.8% at 100 and 1000 cd m−2, respectively, representing the best EL performance ...
