New Y type chromophores were synthesized and the hyperpolarizability can be effectively translated into large electro-optic coefficients in poled polymers.

Electro‐optic (EO) polycarbonates are prepared through copolymerization of diol nonlinear optical chromophores and bisphenol A with bisphenol A bis(chloroformate) in solution. The obtained polycarbonates exhibit good film‐forming properties and good thermal stability. The poled films of the resultant electro‐optic polycarbonates reveal the maximum EO coefficient of 75 pm/V. The obtained poled films also possess better temporal stability. These good performances endow the resultant EO polycarbonates with device application in photonics.
