摘　　要：设计了基于绿色荧光晶态材料的制备与性能的研究性实验。以氯化苄、三(4-甲氧基)苯基膦和氯化锰等为原料,采用溶剂热、超声辐射法和溶剂挥发法制备了四氯合锰-苄基三(4-甲氧基)苯基季鏻盐[BzT(4-MeO)PP]2[MnCl4]晶态材料。用元素分析、红外光谱、紫外-可见光谱、X-射线粉末衍射和单晶衍射仪等手段进行了表征。结果表明,晶态材料属于三斜晶系,P-1空间群;一个不对称单元中含有2个[BzT(4-MeO)PP]^+阳离子和一个四氯合锰[MnCl4]^2-配阴离子,阳离子之间存在C—H…O氢键,而阳离子与阴离子通过C—H…Cl氢键相连。在360 nm紫外光照射下,晶态材料展现绿色荧光。A research experiment forthe preparation and properties of a crystalline material with green fluorescence was designed.Using benzyl chloride,tri(4-methoxy)phenylphosphine and manganese chloride as raw materials,benzyl tri(4-methoxy)phenyl quaternary phosphonium tetrachloromanganate[BzT(4-MeO)PP]2[MnCl4]crystalline material was prepared by solvent heat,ultrasonic radiation and solvent volatilization.It was characterized by elemental analysis,IR,UV-Vis,X-ray powder diffraction and single-crystal diffraction.The results show that the crystalline material belongs to the trine system and the P-1 space group.An asymmetric unit contains two[BzT(4-MeO)PP]^+cations and a tetrachloromanganate[MnCl4]^2-complex anion.There are C—H…O hydrogen bonds between cations,which are connected with and anionsby C—H…Cl hydrogen bonds.Under the ultraviolet light of 360 nm,the crystalline material shows the green fluorescence.
