|Abstract:||Optically active azobenzenedicarboxylic acids were synthesized from l-alanine, and the polycondensation of the diacids with o-, m-, p-xylylenediols, 5-norbornene-2, 3-endo, endo- and exo, exo-dimethanols, m-, p-xylylenediamines, and trans-1, 4-cyclohexanediamine was carried in N, N-dimethylformamide. Polymers with weight-average molecular weights of 3, 300–33, 700 were obtained in 63%-quantitative yields. All the polymers reversibly isomerized the azobenzene units from trans to cis and vice versa upon UV- and visible-light irradiations. The polymers exhibited no evidence for the formation of a chiral secondary structure.|
