以非手性的3-吡啶-4-苯甲酸(HL)为配体,在溶剂热条件下和Zn(Ⅱ)自组装,制得二维配位聚合物[Zn(L)_2]_n·n DMF(配合物1)的纯手性单晶,通过红外光谱、元素分析和单晶X射线衍射测试对配合物1的分子结构进行了表征.在配合物1中,脱去质子的配体阴离子(L)-采取两种手性构象异构体桥联四节点的Zn(Ⅱ),形成纯手性二维网格,并沿c轴堆积成手性的晶体.在310 nm激发光的激发下,固体配合物1在375 nm处具有强的荧光发射.
Two-dimensional coordination polymers [Zn (L) 2] _n · were synthesized by the self-assembly of Zn (Ⅱ) with achiral 3-pyridyl- The complex structure of complex 1 was characterized by FT-IR, elemental analysis and single crystal X-ray diffraction (XRD) .In complex 1, the deprotonated ligand Anion (L) - Two chiral conformers are used to bridge the four nodes of Zn (II) to form a pure chiral two-dimensional grid and deposit chiral crystals along the c-axis. At 310 nm excitation light Upon excitation, the solid complex 1 has strong fluorescence emission at 375 nm.
