摘要

The reaction of a metallo-organic ligand (LA) in which two"V"-shaped bisterpyridines attaching to meta-position of"X"-shaped tetraterpyridine via<tpy-Ru2+-tpy>connectivity and Zn2+ions gave rise to 3D supramolecular architectures:octagram (Zn8LA4). However, a position varied ligand (LB) in which two"V"-shaped bisterpyridines locating at the ortho-position of"X"-shaped tetraterpyridine afforded a different 3D hexagram (Zn6LB3). Full characterizations included NMR (1H, 13C, 2D COSY, NOESY and DOSY), ESI-MS, TWIM-MS, TEM and AFM. The resulted structures were directly determined by the position of two"V"-shaped bisterpyridines attaching to"X"-shaped tetraterpyridine.
