Modeling and scaling of chielectric relaxation of nonlinear optical polymers in frequency domain

chielectric relaxation theory was demonstrated. chielectric relaxation that selectively probes chromophore reorientation in the frequency domain was d escribed by the Havriliak Negami (HN) function. chielectric spectra of seve ral nonlinear optical (NLO) polymers were fitted well by the HN function. T o describe the scaling of chromophore reorientation relaxation in frequency domain, two-shape parameters m and n describing the low- and high-frequenc y wings of the chielectric spectra need to be specified, besides the chiele ctric characteristic relaxation time tau and the chielectric strength Delta chi((2)). From the temperature dependences of m and n of NLO polymers, the relations between the chromophore relaxation and the or relaxation of the polymer host have been revealed.
