Abstract

A compound having nonlinear optical properties of the general formula: Ar1 CR1 CR2 (Ar2 CR3 CR4)n Ar3 (I)wherein, n represents a whole number; R1, R1, R3 and R4 groups are independently selected from H, branched aliphatic, straight chain aliphatic, branched silane or straight chain silane; Ar1 and Ar3 are aromatic radicals having a substituent in at least one position adjacent to a site of attachment of the CC double bond and having at least one electron withdrawing or electron donating substituent in at least one of the remaining positions; Ar2 is an aromatic radical having a substituent in at least one position adjacent to a site of attachment of the CC double bond; with the proviso that the substituent in at least one position adjacent to the site of attachment of the CC double bond and R1, R2, R3 and R4 groups are sufficiently large to cause Ar1, Ar2 and Ar3 to rotate approximately perpendicular to a plane containing each adjacent CC double bond and its substituents and a nonlinear optical device including a compound of the general formula (I).
