Stable Anisotropic Films Obtained by In-Situ Photopolymerization of Discotic Liquid Crystalline Acrylates

New discotic liquid crystals with one, two, or three reactive acrylate end groups were synthesized. They exhibit a wide discotic nematic phase and show spontaneous homeotropic alignment between substrates. The photoinitiated polymerization of these materials was studied. “In-situ photopolymerization...

Zusammenfassung:New discotic liquid crystals with one, two, or three reactive acrylate end groups were synthesized. They exhibit a wide discotic nematic phase and show spontaneous homeotropic alignment between substrates. The photoinitiated polymerization of these materials was studied. “In-situ photopolymerization” of these disklike acrylates leads to transparent and thermally stable films with a negative birefringence.
