Title
Enhanced brightness of 2,6-diphenylthiazolo[4,5-b]pyrazines by introducing double electron donating groups
Abstract

•2,6-Diphenylthiazolo[4,5-b]pyrazines with double electron donating groups were newly prepared.•Some of the new thiazolopyrazines show good fluorescence brightness attributed to enhanced light absorption and high fluorescence yields.•The enhanced fluorescence brightness was explained based on DFT calculations.•The methodology provides the guide to design a new bright thiazolopyrazine fluorophore.

Thiazolo[4,5-b]pyrazine (TPy) derivatives with enhanced fluorescence brightness were developed by tuning the double substituents. The spectroscopic and photophysical properties were investigated by measurements of absorption and fluorescence spectra, fluorescence yields and lifetimes. Based on the DFT calculations, the increased brightness was rationalized by the enhanced electronic absorptivity and fluorescence yields. The developed methodology provides the guide to design high-performance TPy fluorophores.
