MOLECULAR AGGREGATION DECREASE AND CHEMIC AL-REACTIVITY INCREASE OF THE COMPOSITE DEPOSITION OF PHTHALOCYANINE, PARAFFIN, AND NI

Ni was deposited on a co-deposition film of phthalocyanine and paraffi n (Pc Pa) in vacuum, and the composite film (Pc * Pa + Ni) was fabri cated. Molecular aggregation structure and chemical reactivity of Pc o f the composite was investigated in comparison with that of the compos ite film (Pc + Ni) fabricated in a similar way but without Pa. The X-r ay diffraction of Pc Pa showed no peak, and a drastic aggregation de crease to the almost amorphous structure was suggested. The result was different from that of the deposition film of Pc alone which showed h igh crystallinity. The results of XPS measurement supported the above difference. Formation of a NiPc complex was suggested from visible abs orption spectra of dilute solutions of Pc Pai Ni but not from that o f Pc + Ni. The aggregation decrese of PC Pa was considered to increa se the chemical reactivity of Pc and Ni.
