A liquid crystal composition contains a liquid crystal compound; a photo-alignment compound; and a polymer obtained by polymerizing a monomer having two or more radically polymerizable double bonds and one or more hydroxyl groups.

Naphthalene-1-ONN-azoxybenzenes and some unsymmetrically ortho-substituted ONN- and NNO-azoxybenzenes were prepared, and their photochemical behavior in ethanol was compared. The crowded azoxyarenes tend to undergo a facile Wallach rearrangement via the known azoxy-ortho oxygen mirgation and a concurrent pathway involving ONN–NNO isomerization. The relative contribution of the two pathways was affected by substituents.
