摘　　要：按文献方法合成了9-丁基-3-(4,4,4-三氟-1,3-丁二酮基)咔唑(L),以L和三苯基膦为配体与硝酸铜、铜粉反应制备了具有荧光活性的铜(Ⅰ)配合物。利用红外光谱和元素分析表征了配合物的组成。通过单晶X射线衍射分析确定了该配合物的晶体结构,晶体属于单斜晶系,P21/c空间群。晶胞参数:a=1.642 8(5)nm,b=1.043 4(5)nm,c=2.800 1(5)nm,V=4.800(3)nm3,Z=4,Dc=1.313 Mg/m3,R[I>2σ(I)],R1=0.050 1,wR2=0.080 8。该配合物的分子中,β-二酮配体L的2个O原子和三苯基膦配体的P原子参与配位,Cu(Ⅰ)处于畸变四面体配位中心。初步研究了Cu(Ⅰ)配合物的发光性质,配合物在二氯甲烷溶液中有很强的荧光发射。A fl-diketone ligand L （3- （4,4,4-trifluorobutane-1,3-diketone） -9-butylcarbazole ） was synthesized according to literature method. The copper（I） complex with fluorescent activity was prepared by the reaction of copper nitrate, copper, triphenylphosphine and L, which was characterized by elemental analysis and IR spectra. Its crystal structure was determined by single crystal X-ray diffraction analysis. The crystal belongs to monoclinic, P21/c space group. Cell parameters：a r_ 1.6428 （5） nm, b = 1. 0434 （5） nm, c =2. 8001 （5） nm, V=4. 800（3） nm3, Z=4, Dc =1.313 Mg/m3, R [1〉2σ（1）] Rl =0.0501, wR2 =0.0808. The Cu（I.） ion in the distorted tetrahedral copper （I） complex is coordinated by two O atoms from the two β-diketone ligands, and two P atoms from triphenylphosphine, respectively. Fluorescent properties of the copper （I） complex were studied, which indicated that the complex had strong fluorescent emission in dichloromethane solution.
