Abstract

An efficient Sonogashira coupling protocol is developed for tetra-alkynylation at the and -positions of the perylene-monoimide (PMI) dye in its PMI(Br) form. The absorption band for these PMI dyes covered from the visible to Near-infrared (NIR) region and PMI(NMe) is found to exhibit a record-breaking Stokes-shifted NIR emission with good photovoltaic properties.

摘要

开发了一种高效的Sonogashira偶联方案，用于在苝单酰亚胺（PMI）染料的PMI(Br)形式的α和β位置进行四炔基化。这些PMI染料的吸收带覆盖从可见光到近红外（NIR）区域，并且发现PMI(NMe)表现出具有良好光伏性能的破纪录的斯托克斯位移近红外发射。
