Synthesis of oxazetidine substituted perylene dye N-(2,5-di-tert-butylphenyl)-9-(3,3-dimethyl-1,2-oxazetidine-N-yl)perylene-3,4-dicarboximide is reported. The imide moiety present in the reported dye was used to functionalize amino graphene. The 9-(3,3-dimethyl-1,2-oxazetidine-N-yl) perylene-3,4-dicarboximide was used as light harvester for photocatalytic hydrogen generation by covalently attaching on to amino graphene surface. The composite AG-DOPMI/Pt was prepared and found to be an efficient photocatalyts for hydrogen production from methanol:water mixture which can produce 1489 μmol/g hydrogen. The oxazetidine dye gives rise to the production of hydrogen generation even in the absence of sacrificial donor.
