  1. Part I: Search for a correlation between molecular structure and mesogenicity. Part II: Cotton effects of α,β-unsaturated diesters

    … formation and stability. Some p-substituted phenyl esters of acetylenedicarboxylic, fumaric, maleic, mesaconic, cyclohexanedicarboxylic, and benzoic acid were prepared. It was found that deviation from linearity decreased mesophase stability. On the other hand, increased polarizability along …
