Organophosphorus conjugated materials featuring P=C units have been studied in recent years due to their unique optoelectronic properties that might be useful in OLEDs and other optoelectronic devices. Previous studies on benzoxaphospholes (BOPs) reveal their significant photoluminescent properties. In this work, a group of bulky-substituted BOPs were synthesized. Those compounds show comparable photoluminescent properties having enhanced stability compare to less-hindered benzoxaphospholes. Furthermore, we have been working on the incorporation of BOP units into extended conjugated systems. A series of bisbenzoxaphospholes and a trisbenzoxaphosphole were prepared. Photoluminescence studies of these extended conjugated materials will be presented.
