摘　　要：通过元素分析、红外、圆二色光谱等手段表征了配合物[Zn(H2O)(glu)]n.nH2O(1);研究了其倍频效应、热稳定性及气体吸附等性质。圆二色光谱表征表明了其手性特征,固体粉末倍频测试显示1具有中等强度的倍频效应(与KDP相当);热稳定性和气体吸附实验表明1是一种可重复使用的气体吸附材料。该配合物的手性特征引起的倍频效应(非线性光学材料),以及由多孔性特征所引起的气体吸附性能,将为功能分子材料的深入研究提供有益参考。Building functionality in molecule-based materials is a hot focus of research in contemporary materials science.One of the challenges in the field of molecule-based materials is to combine two or more physical properties in the same compound,for example,magnetism and porosity,magnetism and chirality,porosity and chirality materials.Among above bifunctional materials,porously chiral materials are currently a new developing research area with great challenge.A complex,[Zn（H2O）（glu）]n·nH2O（1）,has been characterized by EA,IR,CD spectra,second harmonic generation（SHG）,thermogravimetric（TG）and gas adsorption.The CD signals show the chiral nature of compound 1 which turned out to be SHG-active with the similar intensity to potassium dihydrogen phosphate（KDP）,in agreement with its noncentro-symmetric structure.TG analysis and adsorption behaviors of nitrogen suggest the refreshable attribute of the adsorptional material.This cooperation of the SHG induced by chirality and the gas adsorption property induced by porosity supplies reference for the research of multifunctionally molecular materials.
