Abstract
The pp interaction between phthalocyanines (Pcs) in the solid state induces useful conductivity that is applicable to photoconductors, but it also has disadvantages in terms of reducing the monomeric photochemical properties, i.e., the sharp Q absorption band, intense fluorescence, and ability of singlet oxygen (1Dg) generation. Here, I describe recent methods for preparing silica gel-supported Pcs having both monomeric photochemical properties and high ability of singlet oxygen generation. In particular, magnetic silica gel-supported Pcs can act as the singlet oxygen generator, which can be collected by using magnets.
