在水热条件下,用Cu(Ⅱ)盐与邻菲罗啉(phen)进行反应,得到了三维超分子[Cu2(phen)2(H2O)4].(SO4)2(化合物1).化合物1为单斜晶系,C2/c空间群,晶胞参数:a=4.233(2)nm,b=1.3844(8)nm,c=0.7025(4)nm,β=90.230(7)°,V=4.117(4)nm3,Z=8,R1=0.0898,ωR2=0.1566.化合物1中,两个中心Cu(II)离子均以四配位模式分别形成平面四边形单元[CuN2O2]2+.配离子[CuN2O2]2+与游离的SO42-离子通过静电引力、氢键和π—π堆积作用,将化合物1构筑成三维超分子.荧光测试结果表明,化合物1在270 nm的激发波长下于450 nm处呈现出荧光发射峰.
Under hydrothermal conditions, Cu (Ⅱ) salt was reacted with phenanthroline (phen) to obtain a three-dimensional supramolecular compound [Cu2 (phen) 2 (H2O) 4] 1 is a monoclinic, C2 / c space group with unit cell parameters of a = 4.233 (2) nm, b = 1.3844 (8) nm, c = 0.7025 (4) nm and β = 90.230 = 4.117 (4) nm3, Z = 8, R1 = 0.0898, and ωR2 = 0.1566. In compound 1, the two central Cu (II) ions all form tetrahedrally coordinated quadrilateral units [CuN2O2] 2+ [CuN 2 O 2] 2+ and free SO42- ions constructed compound 1 into three-dimensional supramolecules by electrostatic attraction, hydrogen bonding and π-π stacking.Fluorescence test results show that compound 1 is stable at 450 nm At the fluorescence emission peak.
