This grant is being awarded under the Materials Chemistry                       Initiative.  Work is proposed in which organic materials classes                known to have a large non-linear optical response are                           incorporated into multilayer Langmuir-Blodgett (LB) films.  For                 second harmonic generation, which requires a non-centrosymmetric                structure, LB superlattices are proposed as a scheme to break the               inversion symmetry usually found in LB films.  The work is                      inherently interdisciplinary and combines a chemist and three                   physicist.  It incorporates unique LB growth instrumentation                    (developed at Northwestern), strength in non-linear optical                     measurements, and the chemical and materials expertise of a major               midwest industrials research laboratory (Amoco).
