Abstract

The optical limiting properties of a series of near infrared absorbing 3,5-dithienylenevinylene BODIPY (boron-dipyrromethene) dyes (1-3) that contain donor and acceptor moieties in their π-conjugation systems were studied by using the z-scan technique at 532 nm in the nanosecond pulse range. A strong reverse saturable absorption response was observed when the compounds are embedded into poly(bisphenol carbonate A) polymer thin films, which demonstrates that BODIPY dyes with this type of structure are suitable for use in optical limiting applications.

摘要

通过在纳秒脉冲范围内于532 nm处使用z扫描技术，研究了一系列在其π共轭体系中含有供体和受体部分的近红外吸收3,5-二噻吩基亚乙烯基BODIPY（硼二吡咯亚甲基）染料（1-3）的光限幅特性。当这些化合物嵌入聚（双酚碳酸酯A）聚合物薄膜中时，观察到强烈的反饱和吸收响应，这表明具有这种结构类型的BODIPY染料适用于光限幅应用。
