阴离子主导的手性Cu(Ⅱ)配位聚合物:可逆的结构转换,圆二色谱和二次谐波响应（英文）

Anion-Induced Chiral Cu(Ⅱ) Coordination Polymers:Reversible Structural Transformation,CD Spectra and SHG Response

用手性的V形双齿配体N,N′-((1R,2R)-1,2-二取代环己二胺)双(N-苯甲酸(3-吡啶亚甲基)酰胺(1R,2R)-3-bcpb)和不同的Cu(Ⅱ)盐反应,组装成2个新的手性Cu(Ⅱ)配位聚合物{[Cu((1R,2R)-3-bcpb)]Cl_2}_n(1)和{[Cu((1R,2R)-3-bcpb)_2](ClO_4)2·2H_2O·2CH_3OH}_n(2)。其中1是一维链状结构,2具有二维(4,4)网络拓扑。溶剂热条件下,在甲醇溶剂体系中,通过引入AgClO_4,1能转换成2,同时通过加入NaCl,2也能转换成1。圆二色谱和二次谐波响应测试验证了它们具有结构上的手性。

Two new chiral Cu（Ⅱ） coordination polymers, {[Cu（（1R,2R）-3-bcpb）]Cl2}n（1） and {[Cu（（1R,2R）-3-bcpb）2]（ClO4）2·2H2O·2CH3OH}n（2）（（1R,2R）-3-bcpb=N,N′-（（1R,2R）-cyclohexane-1,2-diyl）bis（N-（pyridin-3-ylmethyl）benzamide））, have been assembled with a chiral V-shaped bidentate ligand and different Cu （Ⅱ） salts, in which 1 is a 1D linear chain, while 2 displays a 2 D（4,4） topology. 1 can be directly transformed to 2 by the introduction of AgClO4, and 2 can also be directly converted to 1 by the addition of Na Cl in methanol under solvothermal conditions. CD spectra and SHG response of the complexes confirm that their bulk samples are both of structural chirality.
