Abstract
A facile and innovative method for the fabrication of highly fluorescent micro-patterns is presented, which operates on the principle of phototriggered phase transition and physical mass migration in the crystalline film of a cyanostilbene-type aggregation-induced enhanced emission (AIEE) molecule ((Z)-2,3-bis(3,4,5-tris(dodecyloxy)phenyl) acrylonitrile) with liquid-crystalline (LC) mesomorphic behavior.
