Platinum Acetylide Materials for Optical Limiting
Abstract
This project explored linear and non-linear optical structure-property relationships for Pt-acetylide oligomers and polymers. These materials show promise for application in laser protection via the reverse saturable absorption (RSA) mechanism. This basic science program had the following primary objectives: 1) Chemical synthesis and purification of new pi-conjugated Pt-acetylide oligomers and polymers. 2) Characterization of the ground and excited state properties of the new materials, with emphasis placed on measurement of parameters that are important to reverse saturable absorption. These parameters include ground state absorption spectra, singlet-triplet intersystem crossing yields, triplet excited state cross sections, and triplet excited state quenching via triplet-triplet annihilation. 3) Evaluate new materials for application as reverse saturable absorbers. The project also explored other key issues, including tuning the spectral region where the ground state and triplet excited states absorb for series of structurally-related Pt- acetylide materials, development of materials that are liquids at ambient temperature, and study of triplet excited state quenching in the solid state.
