  <dc:description>Two zinc phthalocyanine derivatives (ZnPc 1 and 2) carrying bulky 2,6-diisopropylthiophenoxy peripheral substituents have been synthesized and their performances as photosensitizers in photochemical hydrogen production evaluated. To examine the influence of the spacer on the performance of ZnPc 1 and 2, the carboxyl group has been linked to the macrocycle ring either directly or via the phenyl ring, respectively. The photocatalytic activities of ZnPcs (ZnPc 1 and ZnPc 2) as sensitizers of TiO(2 )for hydrogen production were investigated in the presence of Pt. ZnPc 1 and ZnPc 2 sensitized TiO(2 )produced 0.687 mmolg(-1)h(-1) and 0.436 mmol g(-1)h(-1) hydrogens, which also reached 3.986 and 2.091 mmolg(-1) after 8h illumination, respectively, under visible light (&gt;= 420 nm) irradiation. In addition, STH efficiencies of ZnPc 1/TiO2 and ZnPc 2/TiO2 were determined as 1.77% and 1.12%, respectively. ZnPc 1/TiO2 exhibited 1.9-fold more photocatalytic hydrogen amount than ZnPc 2/TiO2, and the hydrogen evolution performance of the photocatalyst in the presence of Pt enhanced to 3.021 mmol g(-1)h(-1) and 0.911mmol g(-1)h(-1) for ZnPc 1 and ZnPc 2, respectively.</dc:description>
