Preparation of Polyviologen-modified TiO2 by Photocatalytic Polymerization of Bis(4-cyano-1-pyridinio)-p-xylene Dibromide

Article abstract of DOI:10.1246/cl.1993.2025

Methylviologen was prepared from 4-cyano-1-methylpyridinium chloride by photocatalytic reduction using TiO2 powder.In the similar manner, insoluble polyviologen was deposited on TiO2 powder by photocatalytic polymerization of bis(4-cyano-1-pyridinio)-p-xylene dibromide.Moreover, polyviologen-polyanion complex modified TiO2 was prepared in the presence of polyanion salt.
