专利号:US-2008004415-A1 优先权日:2004-05-03 标题 :Non-linear optically active molecules, their synthesis, and use 发明人:MCGINNISS VINCENT D; RISSER STEVEN M; DROTLEFF ELIZABETH; JIANG EDWARD; SPAHR KEVIN B 权利人:OPTIMER PHOTONICS INC 摘要:In one aspect, the present invention provides a hyperpolarizable organic chromophore. The chromophore is a nonlinear optically active compound that includes a Ï€-donor conjugated to a Ï€-acceptor through a Ï€-electron conjugated bridge. In other aspects of the invention, donor structures and acceptor structures are provided. In another aspect of the invention, a chromophore-containing polymer is provided. In one embodiment, the chromophore is physically incorporated into the polymer to provide a composite. In another embodiment, the chromophore is covalently bonded to the polymer, either as a side chain polymer or through crosslinking into the polymer. In other aspects, the present invention also provides a method for making the chromophore, a method for making the chromophore-containing polymer, and methods for using the chromophore and chromophore-containing polymer.
