Crystal structure and low-temperature emission of 2,9-dimethyl-1, 10-phenanthrolinebis(triphenylphosphinesulfide)copper(I)
摘要:
The synthesis and crystal structure of a luminescent Cu(l) complex containing triphenylphosphine sulfide and the alpha-diimine 2,9-dimethyl-1,10-phenanthroline (dmp) is described. The coordination geometry about the Cu(I) center is pseudo-tetrahedral. Interplanar interactions between phenyl groups on the phosphine sulfide ligands and the phenanthroline exist, but are significantly less than those previously reported for the Cu(I) triphenylphosphine analog. The complex displays emission from a single metal-centered charge-transfer state at 77K in a 4:1 ethanol/methanol (V/V) glass. This is in contrast to the triphenylphosphine complex, which exhibits dual luminescence from a charge-transfer and an intraligand state at 77K. Crystal data: orthorhombic, P2(1)2(1)2(1), a = 9.4226(9)Angstrom, b = 15.757(1)Angstrom, c = 30.494(6)Angstrom, V = 4527.4(6)Angstrom(3), and R = 0.053 (1021 reflections)

In this paper, we report six phosphorescent Cu(I) complexes with 1,10-phenanthroline-derived ligands and phosphorous ligands, including their synthesis, crystal structures, photophysical properties, and electronic nature. The Cu(I) center has a distorted tetrahedral geometry within the Cu(I) complexes. Theoretical calculation reveals that all emissions originate from triplet metal-to-ligand-charge-transfer

The synthesis and crystal structure of a bimetallic luminescent Cu(I) complex containing 1,4-bis(diphenylphosphinesulfido)butane and the alpha-diimine 2,9-dimethyl-1,10-phenanthroline (dmp) is described. The coordination geometry about the Cu(I) center is pseudo-tetrahedral. Interplanar interactions between phenyl groups on the phosphine sulfide ligands and the phenanthroline exist which are indicative of intramolecular pi-stacking, leading to compressed S-Cu-S bond angles. The complex displays emission from a single metal-centered charge-transfer state at 77 K in a 4:1 ethanol/methanol (v/v) glass. This is in contrast to the triphenylphosphine complex, which exhibits dual luminescence from a charge-transfer and an intraligand state at 77 K. Crystal data: triclinic, P (1) over bar, a = 13.619(4)Angstrom, b = 13.673(2)Angstrom, c = 15.384(2)Angstrom, a = 75.08(1)degrees, beta 80.35(2)degrees, gamma = 80.67(2)degrees.
