摘要

The PI has developed several design approaches for the creation and investigation of organic macromolecules with large 2PA cross-sections important to the goals of the Air Force for optical limiting and sensor applications. The PI s research laboratory has investigated the critical issues in novel macromolecular systems concerning excitation localization and delocalization, disorder and rigidity as well as the role of through space interactions and quinoidal character contribution in these systems. We have also investigated the intersystem crossing process in Pt acetylide complexes in a broad range of temperatures 4.2K-294K. Utilizing the quantum size effects in novel gold and silver nanoclusters will lead to cheap and efficient optical limiters as well as to the development of new generation of twophoton probes for imaging applapplications. Wetinued the systematic investigation of the extraordinary nonlinear optical properties and femtosecond optical excitation dynamics in large oligomeric macromolecules possessing a macrocyclic topology. For these systems we have demonstrated superior two-photon cross-sections per unit molecular weight with very small linear absorption in the transparency window. It paves the way to development of highly concentrated and inexpensive optical limiting materials.
