Abstract
We report N,O-boron-chelated dipyrromethene derivatives exhibiting circularly polarized luminescence (CPL) in the red/near-infrared region, both in solution and the aggregated state. The CPL is originated from the helical chirality through intramolecular substitution of fluorine by an alkenolic substituent. The self-assembly of the fluorophores significantly enhances the || values from 10 to 10.
摘要
我们报告了 N,O-硼螯合二吡咯并甲烷衍生物在溶液和聚集状态下在红光/近红外区域表现出圆偏振发光（CPL）。CPL 源自通过烯醇取代基对内分子取代氟所产生的螺旋手性。荧光团的自组装显著提高了|值，从 10 提高到 10。
