Cuprous Phenanthroline MLCT Chromophore Featuring Synthetically Tailored Photophysics
INORGANIC CHEMISTRY, 55(20), 10628–10636.
Contributors: n, P. Crapps n, C. McCusker n & F. Castellano n
TL;DR:
The disparity in the time scales of pseudo-Jahn-Teller distortion and intersystem crossing between two complexes with different anticipated excited-state geometries suggests that strongly impeded structural distortion in the MLCT excited state enables more rapid surface crossings in the initial deactivation dynamics.

JOURNAL OF PHYSICAL CHEMISTRY A, 119(13), 3181–3193.
Contributors: n, E. Danilov n , C. McCusker n & F. Castellano n
TL;DR:
The molecule with the most inhibited potential for distortion, [Cu(dsbtmp)2](+), possessed the fastest ultrafast dynamics as well as the longest excited state lifetimes in both solvents, illustrating that strongly impeded structural distortion in Cu(I) MLCT excited state enables more rapid surface crossings in the initial deactivation dynamics.
