Programmable Triplet Formation and Decay in Metal Organic Chronophers

Abstract

This proposal is primarily concerned with the design, synthesis, and photophysical characterization of photochemically stable metal-organic chromophores with low-lying triplet excited states, intended to possess systematically variable excited state absorption and emission properties. The main project theme is to investigate alternate pathways to populate long-lived excited triplet states of interest for Air Force applications including power limiting, ultrafast switching, remote identification, and solution-based photon up conversion processes In many instances, metal-to-ligand charge transfer (MLCT) excited states are used to internally sensitize the formation of excited triplet states localized on the appended "organic" system with visible light. Progress has been made in all proposed project areas over the past year's funding period.
