Abstract
The formation of charge-transfer complexes of poly(N-methyl-3-vinylcarbazole (P3VCA) with tetracyanoethylene (TCNE), 2,4,5,7-tetranitro-9-fluorenone (TeNF), chloranil (p-CA), and 1,3,5-trinitrobenzene (TNB) was investigated spectrophotometrically. The association constants (K) of P3VCA complexes were 2.5 to 7.1 times larger than those of the corresponding monomeric analog, N-methyl-3-ethyl-carbazole. To clarify the polymer effect, copolymers of N-methyl-3-vinylcarbazole with styrene and with the dimer model, 1,3-bis[3-(N-methylcarbazolyl)]propane, were studied to obtain the details of the complex formation. The complex of the dimer model was found to be less stable than those of the monomer analog and P3VCA. It is suggested that large stabilities in the polymer system do not simply result from the local concentration effect, but also from the favorable arrangements of the neighboring carbazole units.
