Abstract : The work support by the AASERT award has accomplished the following. (1) It has resulted in the development of syntheses for useful precursors to nonlinear optical materials. In particular extended donor substituted aldehydes have been synthesized. (2) It has yielded new chromophores with large second order nonlinear optical properties. (3) It has explored the utility of synthesizing donor-acceptor substituted thiophene vinylene oligomers for second order nonlinear optical applications. (4) It has studies the application of the two level models derived values of molecular nonlinearities to predict the electro-optical coefficient of poled polymer films containing the same chromophores. (5) It is lead to the development of a new class of highly polarized chromophores by incorporation of a new, very strong acceptor. (6). It has demonstrated that phthalocyanine molecules with heavy metals such as lead can leads to efficient optical limiting in the visible region of the electromagnetic spectrum. Finally it has provided a unique opportunity to provided undergraduate students with a background in chemical research and the fundamental ingredients required for approaching scientific problems.
