摘要

The complexes [Cu(TAABNH(CH_2)_2NH_2)](NO_3) centre dot 2H_2O, (1) [Cu(TAABNH(CH_2)_4NH_2)] (NO_3) centre dot 4H_2O, (2), [Cu(TAABNH(CH_2)_(12)NH_2)(NO_3) centre dot 4H_2O, (3) and [Cu(TAAB(C_(14)H_(10) N_2O_2)_2) centre dot 4H_2O, (4) have been synthesized and characterized by IR, mass spectroscopy, electronic spectroscopy, thermogravimetric analysis and elemental analysis. Electrical conductivity and activation energy evaluation were obtained from study of the temperature dependence of the electrical current (in tablet and thin film). Refraction and reflectance indices, absorption coefficient and optical activation energy were established through ellipsometry and UV-Vis spectroscopy. The electrical conductivity values at room temperature were within the range of semiconducting molecular solids (10~(-6) -10~1 OMEGA ~(-1) cm~(-1)).
