Preparation and Luminescent Property of the Self-Assembled Nanoscale Network Systems Combined Tetracyanoplatinate(II) and Copper(II)-Polyaza Complexes

Complexes 1 and 2 were obtained by the reaction of [Cu(L-1)](ClO4)(2) (1) or [Cu(L-2)](ClO4)(2) (2) (L-1 = 8-acetyl-1,3,6,8,10,13,15-heptaazatricyclo[1 3.1.1.113,15]octadecane, L-2 = 3,7-bis(2-aminoethyl)-1,3,5,7-tetraazabicyclo[3.3.1]decane) with K-2[Pt(CN)(4)] in water. The X-ray crystal structures show that the geometry around Cu(II) ions of 1 and 2 adopts a square-pyramid. Their one-dimensional and two-dimensional structures are constructed by the intermolecular hydrogen bonding between the macrocyclic ligand and anionic complex ions or water molecules and Pt-Pt interaction. They show luminescent property and luminescence quantum yields are 0.341 and 0.187 for 1 and 2 in solid, respectively.
