Novel NLO chromophore with 3, 5-bis(trifluoromethyl) benzoyl as the isolated group in electron bridge was prepared for investigating the NLO character. Chromophore FTC-wl was characterized using UV–Visible spectra, nuclear magnetic resonance, and mass spectrometry and showed us excellent thermal stability. EO films prepared by poly(bisphenol A carbonate) polymer doped with this chromophore at different content had been poled to afford the highest electro optic coefficients (r₃₃) of 28pm/V.
