Abstract The polyetherketone (PEK-c) guest-host system thin films in which the range of the weight percent of 3-(1,l-dicyanothenyl)-l-phenyl-4, 5-dihydro-1H-pryazole (DCNP) is from 20% to 50% were prepared. The predicted high value of electro-optical (EO) coefficient γ33 = 48.8pm/V by using two-level model was obtained when the weight percent of DCNP in the polymer system is 40%.whereas EO coefficients are attenuated at higher chromophore loading than 40%. The temporal stability of the EO activity of the guest-host polymer was evaluated by probing the decay of the orientational order of the chromophores in the polymer system.
