ABSTRACT:
Compositions for use in non-linear optical devices. The compositions have high first molecular electronic hyperpolarizability (.beta.) and therefore display high second order non-linear optical properties when incorporated into non-linear optical devices. The acceptor and donor groups which are used in the compositions, along with the .pi.(pi)-bridge length is chosen to optimize second-order non-linear optical responses.
