Abstract
High-resolution calorimetric investigations have been carried out on the chiral and racemic versions of 4-(3-methyl-2-chlorobutanoyloxy)-4- heptyloxybiphenyl. While the chiral compound shows a weakly first-order Smectic-A-chiral-Smectic-C transition, the racemic one exhibits a continuous Smectic-A-Smectic-C transition. The latter transition is found to be at a mean-field tricritical point, within our experimental resolution.
