π‑Extended Planarized Triphenylboranes with Thiophene Spacers

Planarized triphenylboranes extended with thiophene or bithiophene spacers were synthesized, which showed intense fluorescences in solution and reversible redox waves for reduction in cyclic voltammetry. Organic light-emitting diodes (OLEDs) using these compounds as an electron-transporting material were fabricated.

本研究合成了以噻吩（thiophene）或联噻吩（bithiophene）作为间隔基的平面化三苯基硼烷类化合物，该类化合物在溶液中展现出强烈的荧光特性，且在循环伏安法测试中呈现出用于还原过程的可逆氧化还原峰。以该类化合物作为电子传输材料的有机发光二极管（Organic Light-Emitting Diodes, OLEDs）已被成功制备。
