Abstract: A β-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=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[I>2σ(I)] R1=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.

Key words: (trifluorobutane diketone)butylcarbazole, Catalytic activity
