摘　　要：Main observation and conclusion Photoredox C-H bond formation can proceed in aerobic environment under solar light and has therefore become attractive.Nowa-days,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-C_(3)N_(4)-FITC)film pho-tocatalyst has been reported,which shows ecellent light harvesting ability,and band gap suitability to catalyze the metal free direct C-H arylation of HAs under solar light at ambient temperature.Moreover,the g-C_(3)N_(4)-FITC film photocatalyst can be reused four times without significant loss of activity,confirming the excellent photocatalytic stability.The current strategy to constructa g-C_(3)N_(4)-FITC film photocatalyst for direct C-H arylation opens a new path towards replacing metal-based catalysts in fine chemical Sy nthesis.
