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

J Nanosci Nanotechnol. 2015 Feb;15(2):1389-95. doi: 10.1166/jnn.2015.9320.

Abstract

Complexes 1 and 2 were obtained by the reaction of [Cu(L1)](ClO4)2 (1) or [Cu(L2)](ClO4)2 (2) (L1 = 8-acetyl-1,3,6,8,10,13,15-heptaazatricyclo[13.1.1.113,15]octadecane, L2 = 3,7-bis(2-aminoethyl)- 1,3,5,7-tetraazabicyclo[3.3.l]decane) with K2[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.
