  三氟丙炔基作为氰基配体的替代物，并且从其Rh（III）配合物发出强烈的，室温下，以金属为中心的发射

  摘要：

  所述配体trifluoropropynyl-C≡CCF 3进行了研究作为一个可能的替代物为氰基配体。该类型的复合物的反式- [M（cyclam）（C≡CCF 3）2 ]光学传递函数（其中M =铬3+，钴3+，和Rh 3+ ;光学传递函数=三氟甲磺酸酯）来制备，然后，其特征在于电子光谱和通过循环伏安法测定Co 3+络合物。这三个光谱的紫外可见光谱与反式-M（cyclam）（CN）2 +阳离子具有显着的相似性。Co 3+的三氟丙炔基络合物显示出与其二氰基类似物几乎相同的电化学行为。Rh（III）络合物在室温水溶液中以金属为中心的磷光的量子产率为0.12，寿命为73μs，几乎是其二氰基类似物的10倍。

  Alkynyl complexes of the type trans-[Co(cyclam)(CCR)2]OTf have been prepared and characterized by UV–Vis spectroscopy, 1H NMR, vibrational spectroscopy (infrared and Raman), and cyclic voltammetry. Where appropriate the data is compared to the corresponding Cr(III) and Rh(III) complexes. Though the arylalkynyl ligands have been shown to act as π-donors for the corresponding Cr(III) complexes, vibrational

  During the synthesis of alkynyl complexes of the type [Cr(cyclam)(CCR)(2)]OTf from cis-[Cr(cyclam)(OTf)(2)] OTf, a cis to trans isomerization occurs that is dependent on the identity of the ether solvent. The isomerization occurs to a significant extent in THF, yielding greater than 80% of the trans isomer, whereas in diethyl ether this isomerization occurs to a lesser extent. Though some base catalyzed isomerization of the final alkynyl product occurs, the data herein supports that the majority of the isomerization occurs during the triflate to alkynyl ligand exchange. It is also demonstrated that 1,1,1,3,3-pentafluoropropane can be used in place of the more expensive 1,1,1-trifluoropropyne for the syntheses of the trifluoropropynyl complexes, cis/trans-IM(cyclam)(CCCF3)(2)OTf. The methodologies developed are used to prepare the previously unreported cis-IM(cyclam)(CCCF3)(2)OTf complexes (where M = Cr3+ and Rh-3). Upon photoexcitation, the Cr3+ complex is emissive (738 nm) in room temperature acetonitrile with lifetimes of 24 is and 122 is in air saturated and nitrogen purged solutions respectively. The corresponding Rh3+ complex is non-emissive. (c) 2014 Elsevier BY. All rights reserved.
