The use of compound 1 as an enantiomerically pure neutral and rigid organic linear tecton bearing two divergently oriented monodentate coordinating sites appended with two chiral centres of the same (S) configuration leads, in the presence of neutral metal complexes behaving either as a linear (Cu(hfac)2, Cu(OAc)2) or a V-shaped (HgCl2) 2-connecting node or a 4-connecting square node (NiCl2), to the formation of four homochiral 1- and 2-D coordination polymers.
利用化合物1作为一种对映体纯净的中性且刚性的有机线性构筑单元,其具有两个朝向不同的单齿配位位点,并附有两个相同(S)构型的手性中心,在存在中性金属配合物的情况下,这些金属配合物可以作为线性(Cu(hfac)2、Cu(OAc)2)或V形(HgCl2)的2连接节点,或者作为4连接的方形节点(NiCl2),最终形成四种同手性的1维和2维配位高分子。
