    基于1,4,5,8-四氮杂菲和2,2'-联吡嗪 的钌(ii)配合物的光化学:全面的实验和理论研究†
    摘要:
    在过去的几十年中,已经对聚氮杂芳族钌(II)配合物进行了大量研究,特别是在生物应用范围内,用于开发新的诊断和光疗剂。在这种情况下,在激发时能够与生物分子反应的Ru(II)络合物引起了极大的兴趣。设计基于π缺乏配体的光氧化Ru(II)配合物,例如bpz(2,2'-吡嗪)和TAP(1,4,5,8-四氮杂菲烯),以实现光诱导的电子转移(PET)会在生物分子存在的情况下发生,这要归功于它们具有高度的光氧化作用3MLCT状态。这种PET可以从鸟嘌呤部分(G)或色氨酸残基(Trp)到激发的络合物发生,并最终导致光加合物的形成,即Ru(II)络合物与R (II)络合物之间形成共价键。生物分子的G或Trp部分。在这里,我们报告两个新的光氧化Ru(II)配合物,[Ru(TAP)2 bpz] 2+和[Ru(bpz)2 TAP] 2+的合成,并对其光物理和电化学性质进行研究。得益于针对这些新配合物获得的实验和理论数据,已精确确定了配体bpz

  • Physical, spectroscopic, and biological properties of ruthenium and osmium photosensitizers bearing diversely substituted 4,4′-di(styryl)-2,2′-bipyridine ligands

    Capitalising on the previous identification of a distyryl coordinated Ru(II) polypyridine complex as a promising photosensitizer for photodynamic therapy, eight new complexes were synthesized by modifications of the ligands or by changing the metal coordinated. We report in this work the effects of these modifications on the physical, spectroscopic, and biological properties of the synthesized complexes
    利用先前对二苯乙烯基配位 Ru( II) 的鉴定) 聚吡啶配合物作为一种有前途的光动力疗法光敏剂,通过修饰配体或改变金属配位合成了八种新配合物。我们在这项工作中报告了这些修饰对合成复合物的物理、光谱和生物学特性的影响。二苯乙烯基配体的细微结构修饰仅对相应配合物的可见光吸收和单线态氧量子产率产生中等影响。然而,这些修饰对复合物的亲脂性、细胞摄取和光毒性具有显着影响。尽管复合物的亲脂性对其细胞摄取有某种预期的影响,但最后一个参数不能与其光毒性直接相关,揭示了其他潜在现象。

    goal that requires strong photo-oxidants capable of chloride oxidation. In a molecular approach toward this goal, three ruthenium compounds with 2,2'-bipyrazine backbones were found to oxidize chloride ions in acetone solution. Nanosecond transient absorption measurements provide compelling evidence for excited-state electron transfer from chloride to the Ru metal center with rate constants in excess
    光驱动 HCl 分裂以生产太阳能燃料是一个重要的目标,需要能够氧化氯化物的强光氧化剂。在实现这一目标的分子方法中,发现三种具有 2,2'-联吡嗪主链的钌化合物可以氧化丙酮溶液中的氯离子。纳秒瞬态吸收测量为激发态电子从氯化物转移到 Ru 金属中心提供了令人信服的证据,速率常数超过 1010 M-1 s-1。Cl原子产物被烯烃捕获。这种反应性是通过离子对中基态前体的预组织来促进的。用四阳离子钌络合物氧化氯化物是最有利的,因为双阳离子络合物容易受到光化学配体损失的影响。
  • Syntheses and electronic and optical properties of complexes of the bis(2,2′-bipyrazyl)ruthenium unit
    作者:Benjamin J. Coe、Martyn K. Peers、Nigel S. Scrutton

    Seven new complexes of the form cis-[Ru-II(bpz)2(L-L)(n+) (bpz = 2,2'-bipyrazyl: n = 2; L L = 4,4'-bis (tert-butyl)-2,2'-bipyridyl, 4,4'-dipheny1-2,2'-bipyridyl, 4,4'-dichloro-2,2'-bipyridyl, 4,4'-diamino-2, 2'-bipyridyl, 4,4'-bis(trifluoromethyl)-2,2'-bipyridyl, 4,4'-bis(methoxycarbonyl)-2,2'-bipyridyl: n = 4; L-L = N '',N'"-dimethy1-4,4':2',2 '':4 '',4'''-quaterpyridinium) are prepared and isolated as their PF6- and Cl- salts. Improved methods for synthesising bpz and 4,4'-bis(trifluoromethyl)-2,2'-bipyridyl are described also. Characterisation involves various techniques including H-1 NMR spectroscopy and mass spectrometry. The new compounds are studied alongside the known species where n = 2 and L-L = 2,2'-bipyridyl, 4,4'-dimethy1-2,2'-bipyridyl or 2,2'-bipyrimidine. Their UV-Vis spectra display intense intraligand pi -> pi* absorptions, and also metal-to-ligand charge-transfer (MLCT) bands with two resolved maxima in the visible region. Red-shifts in the MLCT bands occur as the electron-donating strength of L L increases. Cyclic voltammograms show reversible Ru-III/II oxidation waves, and several ligand-based reductions that are also mostly reversible. The variations in the redox potentials correlate with changes in the MLCT energies. Time-dependent density functional theory calculations give relatively good correlations with the experimental UV Vis spectra for selected complexes when using the MOB functional and basis sets Def2-QZVP (on Ru) and Def2-SVP (on all other atoms) in acetonitrile. The lowest energy visible absorption band is confirmed to be due to Ru-II -> bpz MLCT, while further such transitions occur along with MLCT to L L at higher energies. (C) 2015 The Authors.
