摘要

A series of multibranched oligofluorenes with a phosphine oxide center were designed and synthesized through Suzuki cross-coupling reaction. Their thermal, photophysical, and electrochemical properties were investigated. The phosphine oxide linkage can disrupt the conjugation, and then allow the molecule system to extend to improve the solution processability and photoluminescent quantum yields without depreciating the deep blue ...
