Aminopropyl groups on the surface of aminopropylated silica gel were lengthened by grafting of additional propylamine units and applied to immobilize singlet oxygen sensitizers of cationic phthalocyanine series. The photobactericidal function of the supported phthalocyanines was markedly increased along with length of spacer.
