ABSTRACT OF THE DISCLOSURE This invention provides a novel class of quinodi- methane compounds which can exhibit nonlinear optical response. In one embodiment this invention can provide a high performance nonlinear optical substrate which comprises a transparent organic polymer film containing an array of charge asymmetric molecules such as 13,13-diamino-14,14-dicyanodiphenoquinodi- methane: Image Organic materials with large optical nonlinearities find numerous applications, for example in devices adapted for laser frequency conversion, in information control in optical circuitry, as light valves and optical switches.
