Abstrakt: The association of triphenylmethane molecules in a poly( N-epoxypropyl carbazole) solid polymer matrix and its effect on the sensitizing properties of dyes were studied. Associates are formed from ion pairs involving triphenylmethane dyes, a process that can cause a decrease in the sensitizing ability of the dyes with respect to of poly( N-epoxypropyl carbazole). The rate of association depends strongly on the type of the counteranion of the cationic dye [ABSTRACT FROM AUTHOR]
