Phase Separation of Mixed Films of Amorphous Molecular Materials with Quaternary Ammonium Salts: 4,4',4"-Tri(phenothiazinyl)triphenylamine-Tetrabutylammonium Tetrafluoroborate System

摘要

Development of a bottom-up type techniqueand creation of novel materials for thistechnique have become important subjects for supporting the coming super-advanced information society. Recently, phase separation observed for block copolymers hasattracted a great deal of attention. A variety of self-assembled patterns with ordered structures could be obtained usingwell-designed block copolymers[1–7]. Dissipative pattern formation using polymeric systems are also the subject of interest for bottom-up technology. A variety of pattern formation of e.g.,polystyrene[8], amphiphilic polyion complex[9], porphyrine trimers[10], and gold nanoparticle[11]have been reported.
