| Abstract: | A novel bis(β-diketonate)derivate,3,6-bis(4,4,4-trifluorobutane-l,3-dione)-9-n-butylcarbazole 1,was synthesized and structurally characterized by single-crystal X-ray diffrac-tion.The crystal belongs to the monoclinic system,space group P21/c with a=10.961(6),b=22.942(13),C=9.408(6)(A),α=90,β=109.663(9),γ=90°, V=2228(2)(A)3,Z=4,Dc=1.489g/cm3,C24H19F6NO4,Mr=499.40,F(000)=1024 and μ=0.134mm-1.The structure was refined to the final R=0.0699 and wR=0.1627 for 3744 independent reflections(Rint=0.1288)and 1349observed reflections(I＞2o(I)).Compound 1 consists of carbazole unit and two terminal diketonate groups,in which carbazole and its two adjacent diketonate rings are almost coplanar.Moreover,compound 1 was characterized with IR,elemental analysis,1H NMR,MS,electronic absorption,and single-photon fluorescence. |
