Photoinduced anisotropy in an azobenzene ionic liquid-crystalline polymer was investigated through dichroism, birefringence and polarization holography. A dichroism degree of 1.58 and a birefringence value Dn $ 10 À2 were achieved in the polymer film at room temperature, and the polymer film was fou
