A liquid crystalline dendrimer having a cinnamate mesogen containing an azobenzene moiety (D-6AC2) was prepared as an alignment agent of nematic liquid crystals for a planar homogeneous alignment. D-6AC2 is a thermotropic liquid crystal showing smect

Dendronized LC polyacrylate (PA-G1-6PC5) was prepared by the radical polymerization of the 1st generation polypropyleneimine dendron (A-G1-6PC5) having a focal acryloyl and peripheral mesogenic groups. The PA-G1-6PC5 polymer was a thermotropic liquid

A mixture of nematic liquid crystals (NLCs) with a small amount of a polypropyleneimine-based liquid crystalline dendrimer (D-6PC5 and D-6PPCN) exhibited spontaneous homeotropic alignment between the native glass substrates. This dendrimer-induced ho
