  名称：

  Blue-light excitable europium(III) complex based on deprotonated 1-(9-ethyl-6,8-dimethyl-9H-carbazol-2-yl)-4,4,4-trifluorobutane-1,3-dionate and 1,10-phenanthroline

  摘要：

  A new beta-diketone ligand, 1-(9-ethyl-6,8-dimethyl-9H-carbazol-2-yl)-4,4,4-trifluorobutane-1,3-dione was synthesized by four step reaction (Suzuki-Miyaura cross-coupling, Cadogan cyclization, N-ethylation and Claisen condensation reaction) from 1-(4-bromo-3-nitrophenyl) ethanone and 3,5-dimthylphenylboronic acid. Deprotonated 1-(9-ethyl-6,8-dimethyl-9H-carbazol-2-yl)-4,4,4-trifluorobutane-1,3-dionate (L (1)) and 1,10-phenanthroline (phen) coordinated to europium ion to yield a new europium(III) complex, EuL3[phen]. The Eu(III) complex was characterized by elementary analysis, IR, H-1 NMR, C-13 NMR, UV-Vis absorption spectroscopy, thermogravimetric analysis (TGA) and photoluminescence measurements. TGA shows that the decomposition temperature of the complex EuL3[phen] is up to 320 degrees C. Photoluminescence measurement results indicate that the Eu(III) complex exhibits intense red emission and extends its excitation band blue light region. Red emission LEDs were successfully fabricated by precoating complex EuL3[phen] onto 460 nm blue-emitting InGaN chip. The europium complex based on depronated 1-(9-ethyl-6,8-dimethyl-9H-carbazol-2-yl)-4,4,4-trifluorobutane-1,3-dionate is a very interesting blue light excitable red emission material, which can be applied in many fields without UV radiation.
