摘要

Photoredox C-H bond formation can proceed in aerobic environment under solar light and has therefore become attractive.Nowadays,different types of expensive novel metal complexes and nanomaterials have been urbanized as photocatalysts for direct C-H bond formation in between derivatives of heteroarenes (HAs) and aryl diazonium salts.These photocatalysts,however,still suffer from poor stability,high cost,and decay.Herein,a graphitic carbon nitride-based fluorescein isothiocyanate (g-C3N4-FITC) film photocatalyst has been reported,which shows excellent light harvesting ability,and band gap suitability to catalyze the metal free direct C-H anylation of HAs under solar light at ambient temperature.Moreover,the g-C3N4-FITC film photocatalyst can be reused four times without significant loss of activity,confirming the excellent photocatalytic stability.The current strategy to construct a g-C3N4-FITC film photocatalyst for direct C-H arylation opens a new path towards replacing metal-based catalysts in fine chemical synthesis.
