Angewandte Chemie, EarlyView.The excited‐state antiaromaticity of hydroxybenzotropyliums (HBTs) can be tuned through substituent effects to bring the aromatic ‘enol’ (E) and keto (K) tautomers close in energy. This leads to abnormally slow excited‐state proton transfer (on the ns timescale), giving rise to dual fluorescence emission and weak photoacidity.

Donor Extended Blue TADF Dendrimer for High‐Performance Solution‐Processed OLEDs
Advanced Science, EarlyView.A dendronized MR‐TADF emitter, DOBNA‐SpAc‐DCz, was designed to improve solubility, hole transport, and exciton dynamics for solution‐processed OLEDs. Incorporation of ter(tert‐butylcarbazole) dendrons decreases ΔEST and accelerates RISC, yielding short delayed lifetimes (∼2 µs).

Advanced Energy Materials, EarlyView.A wide process window is essential for the commercialization of perovskite photovoltaics. Here, we demonstrate an amorphous π‐conjugated passivator having an asymmetric mono‐iodine substituent on a carbazole moiety imparts a high dipole moment, desirable molecular energy levels, and high thickness tolerance, thereby enabling a wide process window in ...
