2021 journal article

Excited-State Bond Contraction and Charge Migration in a Platinum Dimer Complex Characterized by X-ray and Optical Transient Absorption Spectroscopy

JOURNAL OF PHYSICAL CHEMISTRY A, 125(40), 8891–8898.

By: N. Weingartz *, M. Mara *, S. Roy n, J. Hong *, A. Chakraborty n, S. Brown-Xu*, B. Phelan *, F. Castellano n , L. Chen *

TL;DR: Electronic and nuclear structural dynamics studies of two photoexcited pyrazolate-bridged Pt(II) dimers observe photoinduced electron transfer in 2 featuring a covalently linked NDI acceptor on the ppy ligand, demonstrating how the excited states of these complexes are determined by the overlap of the Pt (dz2) orbitals.

General Design Rules for Bimetallic Platinum(II) Complexes

JOURNAL OF PHYSICAL CHEMISTRY A, 125(43), 9438–9449.

By: A. Mills*, A. Valentine *, K. Hoang *, S. Roy n, F. Castellano n , L. Chen *, X. Li *

TL;DR: Modulating the Pt-Pt distance through the bridging ligand architecture was found to dictate the nature of the lowest energy electronic transitions, localized in one-half of the molecule or delocalized across the entire molecule. (via Semantic Scholar)

2021 journal article

Ultrafast Excited-State Dynamics of Photoluminescent Pt(II) Dimers Probed by a Coherent Vibrational Wavepacket

JOURNAL OF PHYSICAL CHEMISTRY LETTERS, 12(29), 6794–6803.

By: P. Kim *, A. Valentine *, S. Roy n, A. Mills*, A. Chakraborty  n, F. Castellano n , X. Li *, L. Chen *

TL;DR: The results suggest that the ligands could fine-tune the PESs to influence the proximity of the conical intersections of the excited states with the Franck-Condon state and thus to control the branching ratio of the dual ISC pathways. (via Semantic Scholar)

2018 journal article

Excited-State Processes of Cyclometalated Platinum(II) Charge-Transfer Dimers Bridged by Hydroxypyridines

Inorganic Chemistry, 57(3), 1298–1310.

By: A. Chakraborty n, J. Yarnell n, R. Sommer n , S. Roy n & F. Castellano n 

TL;DR: The combined data illustrate that entirely new classes of MMLCT chromophores can be envisioned using bridging pyridyl hydroxides in cooperation with various C^N cyclometalates to achieve photophysical properties suitable for excited-state electron- and energy-transfer chemistry.
