Abstract
Several alkenyl diphenyldiacetylene liquid crystals were synthesized and th eir physical properties evaluated. The introduction of a double bond in the side chain leads to an unexpectedly wide nematic range and an extraordinar ily large figure of merit at elevated temperatures. These liquid crystals a re particularly attractive for infrared laser-beam steering. (C) 2000 Ameri can Institute of Physics. [S0003-6951(00)00433-2].
