    含吡啶基侧基的双-吡啶基铱(III)配合物的合成和pH敏感发光
    摘要:
    摘要制备了一系列铱(III)双-吡啶吡啶配合物,它们在一个或两个叔吡啶(tpy)配体的4'-位掺入侧基吡啶基。这些包括:三个相互异构的同型络合物,其中吡啶基侧基的氮原子与对吡啶的C-C键成对,间或邻。它们的杂配类似物,其中第二个配体是4′-甲苯基-吡啶(ttpy);新配体4'-(2,6-二甲基吡啶-4-基)-吡啶的类似物配合物;以及在叔吡啶和侧基吡啶基之间插入一个附加苯环的相关配合物。在室温下,所有络合物在空气平衡的水溶液中均发光。均配物络合物显示出类似于未取代的[Ir(tpy)2] 3+的结构发射,在这些条件下的发光寿命约为1μs。与[Ir(ttpy)2] 3+相似,杂合类似物提供更宽泛的红移发射光谱,表明这些络合物中的发射主要来自与4'-甲苯基-叔吡啶相关的低能激发态配体。掺入额外苯环的配合物的进一步红移表明,在这些情况下,发射态涉及结合度更高的苯基吡啶基附加的配体。除间位取代的体系外

    The synthesis of 4′-aryl substituted terpyridines by Suzuki cross-coupling reactions: substituent effects on ligand fluorescence
    摘要:
    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。

  • Metal cluster/ruthenium photosensitizer/cobalt phthalocyanine synergistic photocatalytic cycloaddition of carbon dioxide and propylene oxide

    日期:2024.1
    The cycloaddition of CO2 and propylene oxide (PO) is of great significance to green chemistry and resource utilization. Here, two new metal clusters and four ruthenium photosensitizers were synthesized, and a series of composite catalysts were prepared by combining them with cobalt phthalocyanine. Light was introduced into the reaction system and it was found that TON increased from 550 (0 W) to 990
    CO2与环氧丙烷(PO)的环加成对绿色化学和资源利用具有重要意义。这里合成了两种新型金属簇和四种钌光敏剂,并与钴酞菁结合制备了一系列复合催化剂。将光引入反应体系,发现60℃时TON从550(0W)增加到990(200W)。在120°C、200W下,TON高达4616。电子顺磁共振(EPR)实验表明,对于Cat13,光照射会产生电子。将体系注入PO后,光生电子迅速转移至PO。吉布斯自由能计算还表明,通过引入光,该体系更有可能促进PO开环,对CO2环加成表现出优异的催化性能。此外,回收后的催化剂仍能催化CO2与PO生成碳酸丙烯酯。
  • Coordination Synergy between Iridium Photosensitizers and Metal Nanoclusters Leading to Enhanced CO<sub>2</sub> Cycloaddition under Mild Conditions

    photocatalytic CO2 and epoxide cycloaddition under mild conditions such as room temperature and atmospheric pressure is important for green chemistry, which can be achieved by developing coordination synergies between catalysts and photosensitizers. In this context, we exploit the use of coordinate bonds to connect pyridine-appended iridium photosensitizers and catalysts for CO2 cycloaddition, which is systematically
    在室温和常压等温和条件下实现光催化CO 2与环氧化物环加成对于绿色化学具有重要意义,这可以通过催化剂和光敏剂之间的配位协同作用来实现。在此背景下,我们利用配位键连接吡啶铱光敏剂和CO 2环加成催化剂,并通过1 H核磁共振滴定和X射线光电子能谱测量系统地证明了这一点。结果表明,具有配位协同作用的杂化Ir(Cltpy) 2 /Mn 2 Cd 4光催化体系表现出优异的催化性能(产率约98.2%),比对比Ir(Cltpy-Ph) 2 /提高了3.75倍。无配位协同作用的Mn 2 Cd 4体系(收率≈26.2%),条件温和。 Mn 2 Cd 4催化剂与Ir(Cltpy) 2光敏剂之间的配位增强了Mn 2 Cd 4催化剂的光吸收和光响应性能。这已通过瞬态光电流、电化学阻抗和电子顺磁测试得到证实。因此,通过利用温和的条件提高了环加成的效率。

    Two terpyridine derivatives, 4'-(4-(pyridin-4-yl)phenyl)-[2,2':6',2 '']terpyridine (L1) and 4'-(4'-(pyridin-4-yl)-[1,1'-biphenyl]-4-yl)-[2,2':6',2 '']terpyridine (L2) have been synthesized by palladium-catalyzed cross-coupling reactions, and their metal complexes [Zn(L1)(2)](ClO4)(2)center dot 2MeOH center dot CHCl3 (1) and [Cd(L2)(2)] (ClO4)(2)center dot DMF.2.8H(2)O (2) characterized by single crystal X-ray crystallography and spectroscopic methods including electronic absorption and emission measurements. In the crystalline materials, both metal ions have the expected pseudo-octahedral N-6 coordination environment and the lattice structures appear to be influenced by aromatic aromatic interactions involving the heteroaryl tails and the pyridyl rings of the terpyridine units. In solution and in the solid state, the complexes display blue emission attributed to an intramolecular charge transfer transition. (C) 2012 Elsevier Ltd. All rights reserved.

  • 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

    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.
