We report the creation of novel group of the ABDI-BF2 fluorescentdyesbased on the conformationallylocked GFP chromophore. We studied the intramolecular mechanism of radiationless deactivation of ABDI-BF2 fluorophore by introducing the various substituents at the nitrogen atom. The results of this study and our previous work allowed us to claim that in case of ABDI-BF2 this deactivation is determined
utilized in various fluorescence imaging techniques. However, many existing modification strategies could not balance the performance (such as brightness, photostability, water solubility, and permeability) of fluorophores. Herein we report a general strategy to enhance the performance of donor–acceptor-type fluorophores by introducing azetidine-containing heterospirocycles to the commonly used fluorophore
