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 technique and creation of novel materials for this technique have become important subjects for supporting the coming super-advanced information society. Recently, phase separation observed for block copolymers has attracted a great deal of attention. A variety of self-assembled patterns with ordered structures could be obtained using well-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.
