| 英文摘要 | A new cyclometalated ligand 1.3-dimethyl-5-phenyi-1H-[ 1,2,4]-triazole (pdt) was designed and synthesized. And the corresponding it complex Ir(pdt)(2)(phen5f) (phen5f stands for 4,4,5.5.5-pentafluoro-1-(1',10'-phenanthrolin-2'-yl)-pentane-1,3-dionate) was obtained. According to the measurement of the lowest triplet state energy level of Ir(pdt)(2)(phen5o, it is suitable for sensitizing NIR (near-infrared) Ianthanide ions instead of Eu-III. The bimetallic complex [(pdt)(2)Ir(mu-phen5f)YbCl2 center dot 2CH(3)CH(2)OH - H2O]Cl was synthesized by the approach of "complexes as ligands". Data showed that the emission quenching was observed in the solid state when the Ir-III-Yb-III complex was compared with the Ir-III complex, which implied that energy transfer might occur from It complex-ligand to Yb-III ion. Upon irradiation of the MLCT (metal-to-ligand charge transfer) absorption of Ir(pdt)(2)(phen5f), the characteristic emission of Yb-III was obtained with the peak around 978 nm. (C) 2009 Elsevier Ltd.
