Abstract:
An nonlinear optical device comprising:an active element including a chromophore formed as wherein D is an electron donor group; wherein A is an electron acceptor group; wherein a conjugate diene in the bridge structure connects the bridge ring structure and the acceptor A; wherein R=H, F, or any perhalogenated, halogenated or non-halogenated aliphatic or aromatic group with 1-30 carbon atoms functionalized with zero or more of the following functional groups: hydroxy, ether, ester, amino, silyl, and siloxy, and R groups at different positions are not necessarily the same; wherein Râ€²=H, F, or any perhalogenated, halogenated or non-halogenated aliphatic or aromatic group, with 1-30 carbon atoms functionalized with zero or more of the following functional groups: hydroxy, ether, ester, amino, silyl, and siloxy, and Râ€² is not methyl when the two Râ€² groups are the same.
