Synthesis and Spectroscopic Properties of 2,5-Bis(benzoazol-2-yl)pyrazines
摘要:
A class of pi-conjugated 2,5-bis(benzoazol-2-yl)pyrazine dyes have been synthesized in which 2,5-bis(benzimidazol-2-yl)pyrazine (1) exhibits strong fluorescence in solution. The enhanced fluorescence of 1 with a base leads to future applications such as anion sensing feasible upon chemical modification.
