Abstract
AbstractA new electronodonor monomer, N,N‐dimethyl‐p‐aminobenzyl methacrylate (DMABM), was synthesized and radical copolymerized with two electronoacceptor monomers, acryloyl‐ (DNBA) and methacryloyl‐(DNBM) β‐hydroxyethyl‐3,5‐dinitrobenzoate, in order to obtain intramolecular charge‐transfer‐complex copolymers. Also, the small‐molecular models of poly(DMABM), poly(DNBA), and poly(DNBM), the respective acetates, were synthesized and used to measure the values of ionization potential Ip of the donor and the electronic affinity Ea of the acceptor. They are Ip = 7.15 eV and Ea = 1.41 eV. The lower value of Ip as compared with that of carbazole derivatives is taken as evidence of a nonterminal mechanism of copolymerization. Also, from the 1H‐NMR and electronic spectra, the intramolecular complexation is discussed in terms of total transfer of the electron from donor to acceptor structural units.
