Electrophoretic Deposition of Composite Phthalocyanine Films with Inorganic Particles Using Organic Solutions Containing Trifluoroacetic Acid

摘要

フタロシニン（MPc，M=の微粒子（SiO_2，Al_2O_3およびTiO_2）との複合薄膜が，トリプルオロ酢酸を含むジクロロメタン中で生成したMPcのプロトン付加体と無機微粒子の泳動電着により作製された。無機微粒子の正電荷はMPcのプロトン付加体の吸着に起因し，これが泳動されて陰極表面に移動し，プロトンが還元され，MPcと無機微粒子が同時に析出して複合被膜が形成されると考えられた。SEM写真より，得られた薄膜は無機微粒子が均一に分布し，無機微粒子がMPcの結晶により結合されていることが明らかとなった。%Composite blue films of inorganic particles (SiO_2, Al_2O_3 and TiO_2) with phthalocyanine (MPc, M = Cu and Pb) were prepared by electrophoresis of protonated MPc using dichloromethane solutions containing trifluoroacetic acid, particles and MPc. The charging of the particles by the adsorption of protonated MPc species from the solution was ascribed to the electrophoresis of these particles. In this way, composite film of MPc with the inorganic particles was formed. SEM images of the composite film reveal a uniform distribution of the particles throughout the composite film, and most of the particles were bonded by fibrous MPc crystallites.
