Influence of Molecular Aggregation Decrease on the Complex Formation Reactivity in Co-Deposition of Nickel, Phthalocyanine, and Paraffin

A co-deposition of nickel (Ni), phthalocyanine (Pc), and paraffin (Pa) (Ni*Pc*Pa) was prepared by evaporating Ni, Pc, and Pa simultaneously in vacuum. The visible absorption spectrum of a dilute 1-chloronaphthalene solution of Ni*Pc*Pa was compared with that of the co-deposition of Ni and Pc (Ni*Pc)...

Description
Summary:A co-deposition of nickel (Ni), phthalocyanine (Pc), and paraffin (Pa) (Ni*Pc*Pa) was prepared by evaporating Ni, Pc, and Pa simultaneously in vacuum. The visible absorption spectrum of a dilute 1-chloronaphthalene solution of Ni*Pc*Pa was compared with that of the co-deposition of Ni and Pc (Ni*Pc). The nickel phthalocyanine complex (NiPc) formation increased to about 70% in Ni*Pc*Pa, while it was about 50% in Ni*Pc. X-Ray diffraction patterns, electron diffraction patterns, and TEM images showed that the crystallinity and crystallite size of the Pc or NiPc component in Ni*Pc*Pa decrease greatly compared with those in Ni*Pc or in the deposition of Pc alone. These results indicated that the aggregation decrease of the Pc component in co-deposition was found to be one of the most important factors for the reactivity increase for the NiPc formation.
