In this study, we investigated the liquid-crystalline property of the mixtures of 4-butyl-4’-methoxyazobenzene and 4-pentyl-4’-cyanobiphenl (BMAB+5CB) with various BMAB contents, and photoplasticization of poly(methyl methacrylate) (PMMA) using the BMAB+5CB mixtures as photoresponsive plasticizers. We found that a BMAB+5CB exhibited a crystal-like phase at the specific molar ratio of 50/50 mol%. Then, the crystal-like phase transformed into isotropic liquid upon UV-light irradiation at room temperature. By means of the photochemical crystal-like-to-isotropic phase transition, we achieved remarkably large decrease in Tg of PMMA (Tg before photoplasticization
