  Spectral studies of multi-branched fluorescence dyes based on triphenylpyridine core

  摘要：

  A series of novel triphenylpyridine-containing triphenylamine derivatives have been carefully designed and prepared in good yields using the stepwise route reactions. The relationship of photoluminescence property and structure of compounds 9-13 was systematically investigated via UV-vis, fluorescence, thermogravimetric and electrochemical analyzer. The highest occupied molecular orbital and the lowest unoccupied molecular orbital distributions of compounds 9-13 were calculated by density functional theory method. The high fluorescence quantum yields, desirable the highest occupied molecular orbital levels and high thermal stability of compounds 9-13 indicate that the linkage of triphenylpyridine and triphenylamine is an efficient means to enhance hole-transporting ability and fluorescent quantum yield.

  ethers and chalcone derivatives has been discovered. In addition, a related reaction cascade involving dehydrative Mukaiyama aldol followed by a Mukaiyama–Michael addition process has been developed. The later reaction can also be achieved as a three-component coupling reaction. The enantioselective variant of these reactions has been examined with homochiral catalysts. Though these catalysts were active

  一个Ñ -杂环卡宾催化的几个三甲基甲硅烷（TMS）的烯醇醚和查耳酮衍生物之间向山-迈克尔加成已经发现。另外，已经开发出了一种涉及脱水穆凯山山醇醛的随后的反应级联，随后是穆凯山山-迈克尔的加成过程。后面的反应也可以作为三组分偶联反应来实现。这些反应的对映选择性变体已经用同手性催化剂检查过。尽管这些催化剂是活性的，但它们未能实现对映体诱导。

  Four Ru(II)-arene thioamide complexes of the type [(η6-cymene)Ru(PPh3)(L)]+ (L = bidentate monoanionic thioamide ligand) have been synthesized and isolated as their hexafluorophosphate salts. All these complexes are fully characterized by spectroscopic methods. Molecular structures of the ligands (HL2 and HL3) and complex (3) were determined by single crystal X-ray crystallography. The ligands coordinated
