Nowadays, there has been a lot of interest in third-generation organic light-emitting diodes characterized by thermally activated delayed fluorescence (TADF) [1]. Aromatic amine-based molecular glasses belong to the group of charge-transporting and light emitting layer derivatives and are well known in OLEDs field applications [2]. The main advantages of the electroactive low molar mass compounds against polymers are their low melt viscosity, possibility of purification by chromatographic methods and large variety of synthesis methods [3]. In this study, electroactive bipolar derivatives containing 3-(N,N-diphenylamino)-9H-carbazole as donor and (bis)phenylsulfone or benzophenone as acceptor fragments were synthesized and characterized. The structures of materials 1-3 are shown in Figure 1. [...]
