    名称:
    The double-helicate terpyridine silver(I) compound [Ag2L2](SO3CF3)2 (L=4′-phenyl-terpyridine) as a building block for di- and mononuclear complexes
    摘要:
    The double-helicate dinuclear silver(I) complex [Ag2L2](SO3CF3)(2) (1) was obtained by reaction of AgSO3CF3 with 4'-phenyl-terpyridine (L). Each Ag+ ion is coordinated by two N-atoms from one of the ligands and by one N-atom of the other ligand, forming an irregular Ag2N6 bi-triangle geometry, with a metallic bond between the two silver ions. Complex 1 reacts with potentially bidentate ligands (L-1), such as 9,10-bis(diphenylphosphino) anthracene (PAnP), 4,4'-dipyridyl or bis(diphenyl phosphino)methane (DPPM), to give the corresponding dinuclear complexes with bridging L-1, [Ag2L2(mu-L-1)](SO3CF3)(2) (L-1 = PAnP 2, 4,4'-dipyridyl 3 or DPPM 4), whereas on reaction with PPh3 forms the mononuclear complex [AgL(PPh3)](SO3CF3) 5. Reaction of 1 with the potentially tridentate ligand tris(2-diphenylphosphinoethyl)amine (NP3) results in complete decomposition of the coordination spheres to form [Ag(NP3)](SO3CF3) 6. Compound 1 shows a strong fluorescence in the solid state with its excitation band at 383.5 nm, the emission band at 535.5 nm and the lifetime of 4.20 ns, but the derived complexes do not show fluorescent properties. The photoluminescence of 1 in various solvents was also studied. The complexes were characterized by H-1 NMR, elemental analysis, IR, MS, UV and single crystal X-ray diffraction.

  • The synthesis of 4′-aryl substituted terpyridines by Suzuki cross-coupling reactions: substituent effects on ligand fluorescence
    作者:Wendy Goodall、Kerstin Wild、Kathryn J. Arm、J. A. Gareth Williams
    DOI:10.1039/b205330f
    日期:——
    Several 4′-aryl-substituted 2,2′:6′,2″-terpyridines (tpy-C6H4R) have been prepared by palladium-catalysed cross-coupling of 4′-bromoterpyridine or 4′-triflate-terpyridine (triflate = trifluoromethylsulfonyloxy) with aryl boronic acids or esters, RC6H4B(OR′)2 (R = H, m-NH2, p-CHO, -NO2, -CN, -NMe2, -NPh2). The new ligand 4′-mesitylterpyridine (mesityl = 2,4,6-trimethylphenyl) was prepared in the same way. Similarly, 4′-bromophenylterpyridine (tpy-ϕ-Br) has been cross-coupled with aryl halides to generate several new biaryl-substituted terpyridines (tpy-ϕ-C6H4R where R = H, p-CN, NMe2, NPh2), together with two related compounds with pendent 3- or 4-pyridyl groups (tpy-ϕ-C6H4-py). For selected compounds, the alternative coupling strategy of reaction of a terpyridine-4-boronate or terpyridine-4-phenylboronate with the appropriate aryl halide has also been investigated (e.g. to prepare tpy-ϕ-C6H4NO2), but was generally found to be less satisfactory. All of the compounds are fluorescent in the UV region of the spectrum, the biaryl-substituted compounds being only slightly red-shifted compared to the monoaryl systems, but with the further red-shift that accompanies protonation being more significant for the former. Fluorescence lifetimes in solution are in the range 1–5 ns. The emission spectra of the aminobiphenyl-substituted compounds (tpy-ϕ-C6H4NR″2, where R″ = Me or Ph) display a large red-shift with increasing solvent polarity, suggesting the involvement of an intramolecular charge transfer state, as found previously for the two analogues omitting the phenyl ring (tpy-C6H4NR″2). In contrast to the latter, however, protonation or binding of a Lewis acidic metal ion to the aminobiphenyl compounds serves to quench almost completely their emission.
    通过钯催化的交叉偶联反应,制备了几种4′-芳基取代的2,2′:6′,2″-三联吡啶(tpy-C6H4R),涉及4′-溴三联吡啶或4′-三氟甲磺酸酯三联吡啶(triflate = 三氟甲磺酰氧基)与芳基硼酸或硼酸酯的反应,RC6H4B(OR′)2(R = H, m-NH2, p-CHO, -NO2, -CN, -NMe2, -NPh2)。新配体4′-三甲基苯基三联吡啶(mesityl = 2,4,6-三甲基苯基)也通过相同方法制备。类似地,4′-溴苯基三联吡啶(tpy-Φ-Br)已与芳基卤化物交叉偶联,生成了几种新的双芳基取代三联吡啶(tpy-Φ-C6H4R,其中R = H, p-CN, NMe2, NPh2),以及两种含有3-或4-吡啶基侧链的相关化合物(tpy-Φ-C6H4-py)。对于选定的化合物,还研究了替代的偶联策略,即反应一个三联吡啶-4-硼酸酯或三联吡啶-4-苯基硼酸酯与适当的芳基卤化物(例如制备tpy-Φ-C6H4NO2),但通常发现效果较差。所有化合物在紫外区域都有荧光发射,双芳基取代的化合物相比于单芳基系统仅有轻微的红移,但其伴随质子化产生的进一步红移对前者更为显著。溶液中的荧光寿命在1~5纳秒范围内。氨基联苯取代化合物的发射光谱(tpy-Φ-C6H4NR″2,其中R″ = Me或Ph)随着溶剂极性的增加显示出较大的红移,表明存在分子内电荷转移态,这与先前报道的两种省略苯环的类似物(tpy-C6H4NR″2)一致。然而,与后者不同,氨基联苯化合物在质子化或与路易斯酸性金属离子结合时,其发射几乎完全淬灭。

    these complexes correlate well with the Hammett σp substituent constants, showing the systematic effect of remote substitution in the ligand framework. TRIR spectroscopy allowed us to assign the lowest singlet and triplet excited states to a metal-to-ligand charge-transfer (MLCT) character. This result contrasts our previous report on analogous κ2N-tricarbonyl complexes, where remote substitution switched
    六个铼(I)κ 3种Ñ二羰基配合物与4' - (4-取代的苯基)三联吡啶配体在它们的基态和激发态进行评价。通过结合瞬态IR(TRIR),电化学和IR光谱电化学以及随时间变化的密度泛函理论(TD-DFT),研究了这些具有不同给电子强度的取代基(从CN到NMe 2)的配合物。 。它们表现出全色吸收,并且可以比三羰基对应物更强的光还原剂。这些配合物的基态和激发态电势,吸收最大值和寿命(250–750 ps)与哈米特σp很好地相关取代基常数,显示在配体框架中远程取代的系统效果。TRIR光谱使我们能够将最低的单重态和三重态激发态分配给金属到配体的电荷转移(MLCT)特征。这一结果对比我们以前类似κ报告2 ñ-三羰基配合物,其中远程取代将字符从MLCT转换为配体内电荷转移。借助TD-DFT计算,我们剖析了第三个吡啶配位,局部对称性和增加的共轭长度的几何和电子效应。这些结果为具有长寿命三重态激发态的配合

The reaction is mediated by the most abundant metal in the Earth’s crust, aluminum (Al), and depending on the conditions employed, exhibits ionic or radical character as suggested by experimental and computational analysis. In the latter case, intermediate formation of an AlIII complex supported by π-radical
