A series of singlet oxygen sensitizing hybrid materials is reported consisting of a zinc(II) phthalocyanine (ZnPc) derivative immobilized on nanoporous gold leafs (npAu) with various pore sizes. The resulting photocatalytic coatings exhibit a thickness of around 100 nm and pore sizes between 9-50 nm. Herein, we report the synthesis and characterization of those hybrid materials which were synthesized by functionalization of npAu leafs by an azide terminated alkanethiol self-assembled monolayer (SAM) and subsequent copper catalyzed azide-alkyne cycloaddition (CuAAC). The characterization of the samples morphol. included SEM (SEM), UV-Vis spectroscopy as well as energy dispersive X-ray spectroscopy (EDX). The morphol.-reactivity relationship was investigated employing the hybrid photocatalysts in the photooxidation of diphenylisobenzofuran (DPBF) as selective singlet oxygen quencher. An increasing photocatalytic activity was found for smaller pore sizes up to 15 nm, due to the gain in sp. surface area concomitant with an increasing amount of immobilized photosensitizer, completely dominating the effect of the higher spectral overlap caused by the shift of the plasmon resonance of npAu, until mass transport and diffusion limitation gets predominant for pore sizes below 15 nm.1,3-Diphenylisobenzofuran(cas: 5471-63-6Recommanded Product: 1,3-Diphenylisobenzofuran) was used in this study.
