  名称：

  Photophysical properties and computational investigations of tricarbonylrhenium(I)[2-(4-methylpyridin-2-yl)benzo[d]-X-azole]L and tricarbonylrhenium(I)[2-(benzo[d]-X-azol-2-yl)-4-methylquinoline]L derivatives (X=N–CH3, O, or S; L=Cl−, pyridine)

  摘要：

  We report a combined experimental and computational study of new rhenium tricarbonyl complexes based on the bidentate heterocyclic N-N ligands 2-(4-methylpyridin-2-yl)benzo[d]-X-azole (X = N-CH3, O, or S) and 2-(benzo[d]-X-azol-2-yl)-4-methylquinoline (X = N-CH3, O, or S). Two sets of complexes are reported. Chloro complexes, described by the general formula Re(CO)(3)[2-(4-methylpyridin-2-yl)benzo[d]-X-azole]Cl (X = N-CH3, 1; X = 0, 2; X = S, 3) and Re(CO)3[2-(benzo[c -X-azol-2-yl)-4-methylquinoline]Cl (X = N-CH3, 4; X = O, 5; X = S, 6) were synthesized heating at reflux Re(CO)(5)Cl with the appropriate N-N ligand in toluene. The corresponding pyridine set {Re(CO)(3)[2-(4-methylpyridin-2-yl)benzo-X-azole]py}PF6 (X = N-CH3, 7; X = O, 8; X = S, 9) and (Re(CO)(3)[2-(benzo[d]-X-azol-2-yl)-4-methylquinoline]py)PF6(X = N-CH3, 10; X = O, 11; X = S, 12) was synthesized by halide abstraction with silver nitrate of 1-6 followed by heating in pyridine and isolated as their hexafluorophosphate salts. All complexes have been fully characterized by IR, NMR, electrochemical techniques and luminescence. The crystal structures of I and 7 were obtained by X-ray diffraction. DFT and time-dependent (TD) DFT calculations were carried out for investigating the effect of the organic ligand on the optical properties and electronic structure of the reported complexes.

  杂环系统的伏安行为。吡啶基取代的苯并咪唑，苯并恶唑和苯并噻唑

  摘要：

  对于一系列18个吡啶基取代的杂环碱[苯并咪唑，苯并恶唑和苯并噻唑]，已研究了在滴下的汞电极上测得的伏安特性。还研究了通过与碘甲烷反应获得的相应的季盐。发现还原电位取决于苯并咪唑，苯并恶唑或苯并噻唑部分的性质及其在吡啶环上的位置以及正电荷的存在。发现伏安波的可逆性是系统结构的函数。还研究了质子供体对碱的伏安行为的影响。
