THE SYNTHESIS OF DIHEXADECYLVIOLOGENMONTMORILLONITETETRAPHENYLPORPHINE INTERCALATION COMPOUNDS AND THE PHOTOCHEMICAL REACTIONS

抄録

Dihexadecylviologen (1, 1'-dihexadecyl-4, 4'-bipyridinium: 2C₁₆V²⁺)-montmorillonite intercalation compound was synthesized by an ion exchange reaction, and used as a support to accommodate mesotetraphenylporphine. The photoinduced electron transfer from the adsorbed porphine to the 2C₁₆V²⁺ was observed by visible light irradiation. The amphiphilic viologen acted as an electron accepter as well as surface modifier to introduce the porphine into the interlayer space of montmorillonite.
