Abstract

Detailed heat-capacity measurements have been carried out on free-standing liquid-crystal films of n-heptyl-4'-n-pentyloxybisphenyl-4-carboxylate to investigate the nature of transitions related to surface crystal-E order. Distinct thermal hystereses are observed. Upon heating from the temperature range exhibiting surface crystal-E order and interior hexatic order, anomalous effects on the interior hexatic-B-smectic-A transition, which strongly depend on the film thickness, are evident.
