Özet

D.c. and a.c. conductivities of a copper phthalocyanine substituted with four 15-membered tetraazamacrocycles (1) and its pentanuclear complexes are measured as Au/MPc/Au sandwiches in vacuum and in air. Chemical doping with NOBF₄ increases the d.c. conductivity of the order 10². Complexation of the perchlorate salts of Ni^II, Co^II and Cu^II with the macrocycles leads to an increase in the d.c. conductivity of about 10²-10³, but the effects of chloride salts are not so distinct. A.c. conductivities of the phthalocyanines depend on frequency with the empirical formula σ(ω) = A(T)ω^n(T), where n is found to be between 0.37 and 1.20.
