Selective Tuning of the HOMO–LUMO Gap of Carbazole‐Based Donor–Acceptor–Donor Compounds toward Different Emission Colors

Abstract

Abstract Carbazole‐based donor–acceptor compounds with tunable HOMO–LUMO gaps were synthesized by Suzuki and Sonogashira cross‐coupling reactions. Their optical and electrochemical properties were fully characterized. The results show that materials with different emission colors ranging from blue to green to orange could be obtained. The experimental results were also supported by theoretical calculations.
