Amino-benzo-cinnolines “ABCDyes” as versatile cinnoline-based green emitting fluorophores

Abstract

This article presents a new family of cinnoline-based green-emitting dyes, the ABCDyes (Amino-benzo-cinnolines). The multiple synthetic routes to access them allow for high structural diversity. A photophysical study, supported by TD/DFT, explores their solvatochromism mechanism and fluorescence properties across 15 dyes. Some have been successfully used in live cell imaging, highlighting their potential as future imaging agents
