  Coordination entities of a pyrene-based iminopyridine ligand: Structural and photophysical properties

  摘要：

  A pyrene-based iminopyridine ligand L has been prepared and displays the absorption and emission properties expected for pyrene-based derivatives in solution. Ligand L, as well as two neutral and, one monocationic coordination entities, respectively formulated as [ZnLCl2] 1, [ReLCl(CO)(3)] 3 and [CuL2] (BF4) 2, have been crystallized and analyzed by single crystal X-ray diffraction analysis. The corresponding crystal structures indicate the formation of supramolecular architectures generated by offset pi...pi stacking between pyrene fragments and strong C-H center dot center dot center dot pi is interactions in coordination entity 1. For the cationic coordination entity 2, the crystal packing reveals the presence of C-H center dot center dot center dot F and C-H center dot center dot center dot pi interactions and numerous C-H center dot center dot center dot pi contacts interconnecting the molecules into a 3D network. As for coordination entity 3, hydrogen bonding and pi center dot center dot center dot pi stacking link the molecules in a three dimensional manner. Zinc(II) and copper(I) coordination entities have also been studied through isothermal titration calorimetry, which indicate a strong binding and a different stoichiometry for both coordination entities. Photophysical studies of the ligand and corresponding coordination entities show a monomer type pyrene emission and a higher fluorescence quantum yield for the zinc coordination entity 1 as compared with copper 2 and rhenium 3 coordination entities.

  钯催化CO /乙烯基芳烃聚酮合成中立体化学控制的前所未有的共聚单体依赖性

  摘要：

  使用两个pyr标记的亚氨基吡啶（NN '）合成中性和单阳离子钯（II）配合物[Pd（Me）Cl（NN '）]和[Pd（Me）（MeCN）（N） N'）] [PF 6 ]。单阳离子络合物在CO /乙烯基芳烃共聚反应中生成活性催化剂，从而导致聚酮的收率和分子量强烈依赖于N-N'，而酮亚胺催化剂的生产效率比醛亚胺对应物高出一个数量级。发现用醛亚胺催化剂合成的聚酮的立体化学取决于乙烯基共聚单体：主要获得苯乙烯的间同立构共聚物，主要生产4-甲基苯乙烯的全同立构共聚物，形成4-甲基苯乙烯的无规立构大分子叔丁基苯乙烯。统计分析表明，立体化学的控制从对4-甲基苯乙烯的对映选择性位点控制变为对苯乙烯的链端和对映选择性位点控制的组合。

  日期：——

  Two stable diastereomeric atropisomers of a cyclometallated iridium complex containing a pyrene functionalized pyridine imine ligand have been isolated. These are the first fully characterized examples of metal containing atropisomers in which the rotational axis is not between two chelating atoms. The atropisomers can be converted thermally via a rocking motion of the pyrene moiety.
