FUNCTIONALIZED HETEROAROMATICS FOR NLO APPLICATIONS. ABSTRACT Nonlinear optical materials having highly conjugated fused ring structures of two or three aromatic or heteroaromatic rings, at least one of which is a five-membered heteroarmatic ring, or structures of one to four non-fused five-membered heteroaromatic rings. Methods of tricyanovinylating heteroaromatic ring structures to form nonlinear optical materials are also disclosed. Polymers having the disclosed nonlinear optical materials as pendant side chains, which polymers exhibit second order nonlinear optical properties, and base polymers having pendant fused ring structures devoid of nonlinear optical properties that exhibit second order nonlinear optical properties after the covalent attachment of tricyanovinyl groups to the pendant side chains are disclosed. Methods of tricyanovinglating the pendant side chains of the base polymers are also disclosed.
