Hexaalkoxytriphenylene formed hexagonal micronsize islands when the cast film was slowly cooled from the isotropic state. Co-casting of cyanine dyes led to hierarchic structures of fluorophores in the center of the domes, and fluorescence microscopy and microspectrometry confirmed that cyanine J-aggregates were formed. © 2005 The Surface Science Society of Japan. 关键词: Liquid crystals;Dyes;Crystallization;Fluorescence;Photoluminescence;Solar cells;Nanostructured materials;Charge coupled devices;Cameras;Organic light emitting diode (OLED);Cyanine dyes;Diffusion and migration;J-aggregates;Nanostructure chemistry;Processing and fabrication;Aromatics
