Oxidized triangle terarylenes with asymmetric side-aryl units are synthesized, which show photo-induced turn-on yellow luminescence based on photochemical intramolecular ring-cyclization reaction in the solid state. A direct photo-patterning process for organic electroluminescent devices is successfully demonstrated with selective light irradiation through an appropriate mask-pattern.
