摘要:

Twenty esters selected from the first ten homologues of each of the 4′-n-octylbiphenyl-, 4′-n-nonylbiphenyl- and 4′-n-decylbiphenyl-4-yl 5-n-alkylthiophene-2-carboxylates have been examined by X-ray diffraction techniques. These esters show extensive smectic polymorphism, but only tilted phases are observed, all with tilt angles of around 45°
