Abstract

Novel mono phthalocyanines and cofacial bisphthalocyanines were synthesized from 4,4 '-(1a,8b-dihydronaphtho[b]naphthofuro-[3,2-d]furan-7,10-diyl)bis(oxy)diphthalonitrile 1. The products were characterized by elemental analysis, UV-vis, IR, 1H NNIR and mass spectroscopy. Both the direct current (dc) and alternatin current (ac) electrical properties of the product films were investigated as a function of temperature in the frequency range 40-10(5) Hz. It was observed that the ac response of the films can be represented by the omega(s) law. The temperature dependence of dc conductivity showed typical Arrhenius behavior for all compounds.
