Abstract
Official abstract text for this publication.
Nonlinear optical chromophores having one or more diamondoid groups covalently attached to the chromophore, methods of making nonlinear optical chromophores, their use in thin films and electro-optical devices containing such nonlinear optical chromophores and thin films comprising the same.
First claim
Opening claim text (preview).
What is claimed is: 1. A nonlinear optical chromophore of the general formula (I): D-π-A (I) wherein D represents an organic electron-donating group; A represents an organic electron-accepting group having an electron affinity greater than the electron affinity of D; and π represents a π-bridge between the organic electron-accepting group and the organic electron-donating group; wherein the π-bridge between the organic electron-accepting group and the organic electron-donating group has the following formula (II d ): wherein each Y independently represents a sulfur linked aryl group of the following formula (II 1 ): wherein each a and b independently represents an integer of 0 to 3; and z represents an integer of 1 to 3; the nonlinear optical chromophore comprising one or more diamondoids, wherein each of the one or more diamondoids is covalently bound to one of the organic electron-accepting group, or the organic electron-donating group. 2. A nonlinear optical chromophore of the general formula (I): D-π-A (I) wherein D represents an organic electron-donating group; A represents an organic electron-accepting group having an electron affinity greater than the electron affinity of D; and π represents a π-bridge between the organic electron-accepting group and the organic electron-donating group; wherein the π-bridge between the organic electron-accepting group and the organic electron-donating group has the following formula (II d ): wherein each Y independently represents a sulfur linked aryl group of the following formula (II 2 ): wherein each a and b independently represents an integer of 0 to 3; and z represents an integer of 1 to 3; the nonlinear optical chromophore comprising one or more diamondoids, wherein each of the one or more diamondoids is covalently bound to one of the organic electron-accepting group, or the organic electron-donating group.
