文摘

Full homologues series of 4-alkoxyazobenzene chlorides was synthesized. Unexpected liquid-crystalline properties were discovered and investigated. Kinetic constants of photoisomerization process were calculated. Influence of the molecule length on mesomorphism and photoisomerization rate were defined.
