A new ligand 4′-phenyl-4,2′:6′,4″-terpyridine and its 1D helical zinc(II) coordination polymer: syntheses, structures and photoluminescent properties
摘要:
A new ligand 4'-phenyl-4,2':6',4"-terpyridine (L) and its zinc complex [Zn(L)Cl-2](n) (1) have been prepared and structurally characterized by single-crystal X-ray diffraction. In 1, the ligand L, with three non-planar pyridyl rings, links two zinc ions through two terminal pyridines to construct a 1D helical polymer chain, the intrachain Zn...Zn distance is 13.040 Angstrom. Both L and 1 display strong photoluminescence in the solid state at room temperature. (C) 2004 Elsevier B.V. All rights reserved.
