Abstract

Null transmission ellipsometry and depolarized reflected light microscopy have been performed on freestanding films of two achiral meta-substituted three-ring compounds. These compounds exhibit two different tilted smectic phases, SmC1 and SmC2. Our studies confirmed previous results obtained from another achiral meta-substituted three-ring compound that the SmC1 and SmC2 phases are SmC and SmCA, respectively.
