Abstract

Summary: A simple sonochemical approach has been successfully developed to deposit poorly dissolved phthalocyanine dyes onto the surface of a highly‐ordered mesoporous nanostructured TiO~2~ thin film. The aggregation‐free phthalocyanines are effectively encapsulated and stabilized in the nanopore arrays of the zeolite‐like mesoporous nanocrystalline TiO~2~ thin film. Highly dispersed dye∥TiO~2~ heterojunction arrays with a large contact area can be obtained by using this interesting approach.

The incorporation of phthalocyanine dyes into the surface of a highly‐ordered mesoporous nanostructured TiO~2~ thin film, a potential photocatalyst.
