“…Copper(I) diimine coordination complexes (denoted [Cu I (NN) 2 ] + ) have a long, rich history that parallels that of their transition-metal cousins, polypyridyl ruthenium(II) systems [1][2][3][4][5][6][7][8][9][10][11] . Current interest is driven by a desire to employ transition metal coordination complexes in applications from solar energy conversion 12 to chemical sensing 13,14 and molecular devices.…”

“…It has been shown that the presence of bulky groups at 2,9 positions can block solvent access to the Cu center to prevent the formation of an "exciplex", lowering the energy gap between the MLCT and the ground states and accelerating the ground state recovery, and thus result in a longer MLCT lifetime and a higher emission quantum yield. 14,15,18,[26][27][28][29] These studies suggest that the excited state dynamics of Cu I diimine complexes could be controlled by the dihedral angle between the two phenanthroline ligand planes as well as the solvent accessibility to the Cu center. Previously, we have investigated the structural influence on the excited state dynamics in an extreme case of a completely locked tetrahedral coordination geometry due to the stericallybulky t-butyl groups in bis(2,9-di-tert-butyl-1,10-phenanthroline)- 19 We showed that [Cu…”
