Second Generation Organometallic Materials for Non-Linear Optical Application

Abstract

The primary focus of this program was to synthesize pi-conjugated oligomers that feature high cross section two-photon absorbing (TPA) chromophores combined with transition metal centers. The TPA chromophores imbue the oligomers with high cross sections for two-photon absorption, whereas the metal centers provide for efficient production of long-lifetime, strongly absorbing triplet excited states. Because of the strong absorption of the triplet excited states, the materials display reverse saturable absorption (RSA). The second generation organometallic materials provide efficient, broad wavelength and broad temporal response nonlinear absorption via a dual mode TPA/RSA mechanism.
