• The micelle of 1-lauryl-3-carbamoylpyridinium bromide(NLaN) and poly-1-(<I>p</I>-vinylbenzyl)-3-carbamoylpyridinium chloride (PVCG) were shown to form charge transfer complexes with dihydronicotinamides and several aromatic compounds in aqueous media. A broad charge transfer absorption at longer wavelengths was easily detected, and the association constant of 1 : 1 complexes which was estimated from the CT band was enhanced by 6.2–220 times in the NLaN micelle and by 14–66 times in the polymeric system, compared with non-micellar, monomeric system. The enhancement of the interaction between NLaN and its reduced from (NLaNH) was similar in the CTAB micelle and in a nonionic micelle. The increased electron-acceptabilities of the pyridinium group in micellar and polymeric systems were discussed in reference to NAD coenzyme.
