Abstract

Abstract : A series of SubPcs comprising a carboxylic acid anchoring group at the peripheral (SubPc 1–2 ) or axial position (SubPc 3 ) were synthesized and used as sensitizers for photocatalytic H2 production, for the first time. Abstract : A series of SubPcs comprising a carboxylic acid anchoring group at the peripheral (SubPcs 1, 2 ) or axial position (SubPc 3 ) were synthesized and used as sensitizers for photocatalytic H2 production, for the first time. SubPc 3 /TiO2 shows the best photocatalytic activity with a hydrogen evolution rate of 1396 μmol h −1, which is much higher than that of SubPcs 1 and 2 (771 and 658 μmol g −1, respectively). This work clearly shows that considering their optical and redox properties, SubPcs are promising candidates for light-driven water splitting systems.
