    一种改善含三齿配体的 Ru(II) 配合物室温发光性能的策略
    摘要:
    已经制备了几种具有新三齿聚吡啶配体的钌 (II) 配合物,并研究了它们的光物理性质。新的三齿配体是 tpy 修饰的系统 (tpy = 2,2':6',2''-三联吡啶),其中引入了设计为与 tpy 部分共面的芳族取代基,目的是增强受体的离域化潜在发光金属到配体电荷转移 (MLCT) 状态的配体并增加 MLCT-MC 能隙(MC = 金属中心激发态)。事实上,用这种新的三齿配体家族获得的 Ru(II) 配合物在室温下(高达 200 ns)显示出长寿命的发光。

In addition, the energies of the (1)MLCT/ (1)LLCT absorption and the (3)MLCT emission bands exhibit a linear correlation with the Hammett constant (sigma p) of the 5'''-substituent on the pyrimidyl ring. The lifetime of the (3)MLCT emission at room temperature is governed by the energy gap law. The triplet transient difference absorption spectra of 1a- 5a exhibit a broad absorption band from

    A new series of ruthenium(II) complexes, based on 4'-(9-anthryl)-2,2':6',2"-terpyridine (an-tpy), have been synthesized from the Ru(III) precursor (an-tpy)RUCl3 (4). These new Ru(II) complexes, [(an-tpy)Ru(tpy-pm-R)) (R = H, 3a; Cl, 3b; phenyl, 3c; p-bromophenyl, 3d), have extended pi-conjugation through the 5'-substituted pyrimidyl group, and have been characterized by analytical and spectroscopic methods, and X-ray single crystal structure determination for 3b and 3d. Luminescence lifetime measurements have shown that the anthryl chromophore greatly increases room temperature (r.t.) excited-state lifetime, even though it is not directly connected to the ligand involved in the metal-to-ligand charge transfer ((MLCT)-M-3) emitting state. This result demonstrates that an equilibrium is established between the anthryl triplet state ((3)an) and the (MLCT)-M-3 state even though the two chromophores are physically separated by more than one nanometer. At low temperature in rigid matrix, such equilibrium does not take place and emission arises from both (3)an and (MLCT)-M-3 excited states. The temperature dependence of the excited-state equilibration induces a temperature switch from single (room temperature) to dual (77 K) emission behavior. (c) 2006 Elsevier B.V. All rights reserved.

    state). Indeed, the Ru(II) complexes obtained with this new family of tridentate ligands exhibit long-lived luminescence at room temperature (up to 200 ns). The enhanced luminescence properties of these complexes support this design strategy and are superior to those of the model Ru(tpy)22+ compound and compare favorably with those of the best Ru(II) complexes with tridentate ligands reported so far.
