Facile synthesis and electro‐optic activities of new polycarbonates containing tricyanofuran‐based nonlinear optical chromophores

Abstract

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.

Construction of a simple crosslinking system and its influence on the poling efficiency and oriental stability of organic electro-optic materials

“…However, due to the movement activity of the chromophore being reduced, the best orientation of the chromophore is difficult to achieve. [12][13][14] "Click-chemistry", based on Diels-Alder reactions, has emerged as a powerful strategy to construct NLO polymers. [15][16][17][18][19] Synthetic advantages of this approach include excellent conversion efficiency, mild reaction conditions, and compatibility with the poling process.…”
