Carbazolyl-Substituted Benzoic Anhydrides as Efficient Triplet Harvesters for High-Brightness Blue Organic Light-Emitting Diodes

Abstract A simple and efficient synthetic strategy for the preparation of carbazole-basedC2-symmetric anhydrides with donor−acceptor−donor (D−A−D) architecture is presented. Four benzoic anhydrides incorporating carbazole or 3,6-di-tert-butylcarbazole donor units, linked to the a...

BilayeredTwo-Dimensional Hybrid Perovskite with SwitchableDielectric Properties, Persistent Disorder, and Narrow-Band Emission

Abstract Two-dimensional (2D) multilayered lead halide perovskites have shown great potential for application in optoelectronics. Here, single crystals of 2D perovskite IPA2FAPb2Br7 (IPA = isopropylammonium, FA = formamidinium) were grown, and the phase transition mechanism, vibr...
