Abstract
We report the synthesis and evaluation of new highly polar molecules whose combined non- linear and linear optical properties are of interest for frequency doubling. The generic scheme for the syntheses rests on enamine substitutions of tetracyano-p-quinodimethane (TCNQ). In the case detailed, a novel reaction product is reported from the unexpected reaction of triethylamine and TCNQ. In polar solvents such as DMF, the molecule has a charge separated ground state and a measured bipole moment of 45 D. Also in polar solvents, the value for the resonant (beta) coefficient is measured to be -190 X 10-30 esu. Coupled with acceptable transparency at 460 nm ((epsilon) equals 86 M-1 cm-1) this molecule points to a new approach in the design of such materials.This publication has 0 references indexed in Scilit:
