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 …

The synthesis of new electro-optic polymers.
… a high degree of electron delocalization. Copolyesters were synthesized by copolymerization of these monomers with methyl 12-hydroxydodecanoate by the standard two-stage, high-temperature polyesterification procedure. The copolyesters, incorporating dipolar units all pointing in the same …

Design, synthesis and fluorescent characterisation of 2,5-dihydro-1,2,3-triazines
… 1,3-dipolar cycloaddition between 2,4,5-triphenyl-1,2,3-triazolium-1-arylaminide 1,3-dipoles and terminal alkyne propiolates. The initial cycloadduct undergoes a sigmatropic rearrangement followed by a ring expansion to generate the 2,5-dihydro-1,2,3-triazine fluorophore. The synthesis of …
