  Synthesis and properties of Re(I) tricarbonyl complexes of 6,6′-disubstituted-4,4′-bipyrimidines with high energy excited states suitable for incorporation into polynuclear arrays

  摘要：

  A series of complexes [(N-N)Re(CO)(3)X](n) (N-N = 6,6'-diaryl-4,4-bipyrimidine, axial ligand X = Cl, MeCN, 4-phenyl-pyridine, or t-Bu-pyridine) have been synthesized and characterized. The substituent aryl on the bipyrimidine, as well as the axial ligand X, has important effects on the properties of these complexes. The co-planarity of the 4,4'-bipyrimidine core and its substituents contributes to the extent of pi-electron delocalization and, hence, to the redox and spectroscopic properties of the complexes. The complexes exhibit Re-to-bpm metal-to-ligand charge transfer absorptions in the range of 379-464 nm, which are red-shifted with the increase in the delocalization in the substituted bpm ligand and the increase in the donor character of the axial ligand. The electrochemical data support metal-based oxidations (from +1.07 to +1.40 V) and ligand-based reductions (from -0.62 to -0.75 V) and correlate well with those obtained by UV-Vis spectroscopy. The X-ray crystal structures of two of the complexes have also been investigated. (c) 2005 Elsevier B.V. All rights reserved.

  通过自由基阴离子偶联合成一系列新型 6,6'-二取代 4,4'-双嘧啶：用于配位化学的新型 π 受体配体

  摘要：

  一个新的 6,6'-二取代 4,4'-联嘧啶配体家族已被制备和表征。通过循环伏安法测定的新配体的还原电位表明，这些新配体是比普遍存在的 2,2'-联吡啶配体更好的 π-受体，甚至优于未取代的母体 4,4'-联嘧啶配体。4,4'-联嘧啶的 6,6' 位置的取代基也会导致整个 UV 区域的 ππ* 和 nπ* 吸收发生红移。双嘧啶家族成员的 X 射线晶体结构表明，芳基取代基在固态时可以与嘧啶环共面。嘧啶环上的芳基取代基提供的额外电子离域作用有助于这些化合物更好的接受 π 能力。(© Wiley-VCH Verlag GmbH & Co.

  Heteroleptic complexes [Ru(bpy)(2)(R(2)bpm)](2+), where bpy = 2,2'-bipyridine and R(2)bpm = 6,6'-diaryl-4,4'-bipyrimidine, have been synthesized and characterized, together with the homoleptic complex [Ru(R(2)bPM)3](2+), in which R(2)bpm = 6,6'-diphenyl-4,4'-bipyrimidine. The substituent aryl on the bipyrimidine has significant effects on the properties of these complexes as compared to the parent [Ru(bpy)(2)(bpM)](2+) complex. The complexes exhibit Ru-to-bpm charge transfer (CT) absorptions centered at about 540 nm and Ru-to-bpy CT absorptions centered at about 435 nm. The assignment of the low energy absorptions is supported by the relative ease of the reduction of the new complexes as compared to [Ru(bpy)3](2+). The new complexes exhibit a relatively intense emission at room temperature, with lifetimes in the 10-50 ns range, with the homoleptic species exhibiting the higher-energy (maximum at 724 nm) and the longest-lived (tau = 48 ns) emission among the complexes. Luminescence lifetimes and quantum yields are governed by the energy gap law, indicating that direct deactivation to the ground state is the dominant relaxation pathway for 1-6, while thermally activated processes are inefficient.
