Outline of Final Research Achievements

The thermal behavior of 1,2,4,5-tetracyanobenzene (TCNB) was measured under vacuum to atmospheric pressure conditions. We investigated the synthesis of 2,3,9,10,16,17,23,24-octacyanophthalocyanine (MPc(CN)8) molecules and the growth of MPc(CN)8-M nanorods on ultrathin metal (Cu, Fe, Ni : 6nm) films in vacuum by chemical vapor deposition (CVD). MPc(CN)8 molecules were synthesized and MPc(CN)8-M nanorods were formed on all substrates. Among them, CuPc(CN)8 molecules were synthesized in high yield, and CuPc(CN)8-Cu nanorods were deposited uniformly and in high density. These results can be explained by the stability of the MPc(CN)8-M complex, the oxide formation on the metal thin films, and the diffusion of metal atoms during the reaction.
