A series of phenanthrene-fused N₂O-type boron-dipyrrin complexes (BODIPYs) with various substituents were synthesized. The synthesized BODIPYs show light absorption and emission in the red to near-infrared region due to their extended π-system. Furthermore, the first optical resolution of the N₂O-type BODIPY was achieved using the phenyl-substituted complex. The separated enantiomers are stable to racemization at room temperature, and exhibited a Cotton effect in the deep-red region.

菲稠合N ₂ O型BODIPYs的合成与手性

合成了一系列带有各种取代基的菲稠合的N ₂ O型硼-双吡啶配合物（BODIPYs）。合成的BODIPY由于其扩展的π系统，在红色至近红外区域显示出光吸收和发射。此外，使用苯基取代的配合物实现了N ₂ O型BODIPY的第一光学拆分。分离的对映异构体在室温下对消旋稳定，并在深红色区域表现出棉花效应。
