Second order nonlinear optical properties of Cu(dppb)(pz(2)Bph(2)), where dppb = 1,2-bis(diphenylphosphino)benzene and pz(2)Bph(2) = diphenyl-bis(pyrazol-1-yl)borate were investigated. In particular, optical second harmonic was generated with different polymer films containing dc-electric field aligned chromophore molecules. It was shown that in such dc-electric field aligned polymer films, the enhancement of the second order output efficiency may be up to 3 times higher with as compared to the non-aligned poly(methylmethacrylate) (PMMA). After switching off the external dc-electric field the second order susceptibility decreases within 5-7 min by about 40 % with respect to the photoinduced ones. After that time, the second harmonic generation efficiency remains constant for much more than a few hours.
