Electron and energy transfer from CuI MLCT excited states

Ultrafast Structural Rearrangements in the MLCT Excited State for Copper(I) bis-Phenanthrolines in Solution

“…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.…”

Investigation of charge transfer and structural distortions during photo-inducted excitation of cuprous bis-2,9-dimethyl-1,10-phenanthroline complex by density functional theory

“…1(a)), displays an visible excitation with enhanced emission lifetime and has remarkable excited state properties that can be comparable to RuðbpyÞ 2þ 3 [13,14]. Several relating researches have proved that the photo-induced electron transfer (ET) and charge separation occur during the irradiation of light energy for this complex [15][16][17]. It is concluded that in order to adapt the electronic density redistribution, this photo-induced electronic movement will cause nuclear movements in the complex, which lead up to distinct variation of structure, or reorganization.…”

Self-assembly of discrete metallosupramolecular luminophores

“…Such complexes have proven to be emissive even in strongly coordinating solvent such as methanol and acetonitrile. The extent to which the emissive properties may be tuned bodes well for device applications, as does the fact that the excited state of such Cu(I) complexes leads to more powerful reductants than that of their Ru(bpy) 3 counterparts, which leads to potential applications as electroluminescence devices [26,27], photovoltaic devices [28], catalysts, and DNA intercalators [29].…”
