摘要：

A rapid access to a series of N-heteroarene fluorophores has been developed on the basis of the palladium-catalyzed direct oxidative C-H/C-H coupling of imidazo[1,2-a]pyridines with thiophenes/furans. The photophysical properties-structure relationship was systematically investigated. The resulting N-heteroarene fluorophores present colortunable emissions (lambda(em): 431-507 nm in CH2Cl2) and high fluorescence quantum yields (up to 91% in CH2Cl2).
