Effect of the Phase Transition of Smectic Liquid-Crystalline Solvent on the Thermal Isomerization of 5,5'-Dialkylthioindigo Compounds

Article abstract of DOI:10.1246/cl.1999.587

The rates and the activation parameters for the thermal cis-to-trans isomerization of 5,5'-dialkylthioindigo dyes embedded in a smectic mesophase of butyl stearate were affected by the transition of the liquid-crystalline to the isotropic phase, depending upon the alkyl length.
