Abstract

An anthracene unit was successfully fused to the zigzag edge of a boron dipyrromethene (BODIPY) core by an FeCl(3)-mediated oxidative cyclodehydrogenation reaction. Meanwhile, a dimer was also formed by both intramolecular cyclization and intermolecular coupling. The anthracene-fused BODIPY monomer 7a and dimer 7b showed small energy gaps (∼1.4 eV) and near-infrared absorption/emission. Moreover, they exhibited high photostability.

摘要

通过 FeCl3 介导的氧化环脱氢反应，成功地将蒽单元融合到硼二吡咯亚甲基（BODIPY）核心的锯齿边缘上。同时，通过分子内环化和分子间偶联也形成了二聚体。蒽融合的 BODIPY 单体 7a 和二聚体 7b 表现出较小的能隙（~1.4 eV）和近红外吸收/发射。此外，它们表现出高的光稳定性。
