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=1.6428(5) nm,b=1.0434(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.
