Conformationally Restricted Aza‐BODIPY: Highly Fluorescent, Stable Near‐Infrared Absorbing Dyes

Weili Zhao, Erick M. Carreira

Abstract

Novel NIR fluorescent, conformational restricted aza-dipyrromethene boron difluoride (aza-BODIPY) dyes were prepared by an efficient process. Such conformational restricted aza-BODIPY dyes possess intense absorption, strong fluorescence, high chemical and photostability. Additionally, the sharp fluorescence of non-amine containing aza-BODIPY dyes is insensitive to solvent polarity.
