Long-lived triplet excited state in a platinum(ii) perylene monoimide complex

Yarnell, J. E., Chakraborty, A., Myahkostupov, M., Wright, K. M., & Castellano, F. N. (2018, January 1). Dalton Transactions, Vol. 47, pp. 15071–15081.

topics (OpenAlex): Organic Light-Emitting Diodes Research; Photochemistry and Electron Transfer Studies; Luminescence and Fluorescent Materials
TL;DR: The synthesis and solution based photophysical properties of a new Pt(ii)-terpyridine complex coupled to a perylene monoimide (PMI) chromophoric unit through an acetylene linkage resulted in quantitative quenching of the highly fluorescent PMI chromophore by introducing metal character into the lowest energy singlet state, thereby leading to the formation of a long-lived PMI-ligand localized triplet excited state.
