• Photophysical and optical power limiting behaviors of Au(I) acetylides with diethynyl aromatic ligands showing different electronic features
  作者：Boao Liu、Zhuanzhuan Tian、Feifan Dang、Jiang Zhao、Xiaogang Yan、Xianbin Xu、Xiaolong Yang、Guijiang Zhou、Yong Wu

  日期：2016.2

  Three Au(I) acetylides have been prepared by coupling (PPh3) AuCl to the diethynyl aromatic ligands with different electronic features under mild condition. Their photophysical properties and optical power limiting (OPL) behaviors have been investigated in detail. The emission characters of the Au(I) acetylides can vary dramatically by exhibiting either singlet or triplet emission signal through changing the chemical structures of the diethynyl aromatic ligands. In addition, the OPL behaviors of the Au(I) acetylides are also affected by the diethynyl aromatic ligands to show different OPL mechanism. It has been shown that the diethynyl aromatic ligand with neither electron-rich nor electron-deficient features should benefit the OPL performance of the Au(I) acetylides in view of both OPL activity and transparency. Furthermore, the Au(I) acetylides can show comparable or even better OPL performances than the state-of-the-art C-60, indicating their great potential in the field of laser protection. All the obtained results should provide valuable information for design high performance OPL materials based on Au(I) acetylides. (C) 2016 Elsevier B.V. All rights reserved.
• Alternating Aromatic and Transannular Chromophores with and without Linker:  Effect of Transannular π−π Interaction on the Optical Property of Dithiaparacyclophane-based Copolymers
  作者：Weiling Wang、Jianwei Xu、Yee-Hing Lai、Fuke Wang

  DOI：10.1021/ma035902+

  日期：2004.5.1

  A series of bithiophene-cyclophane (PPP-type), acetylene-fluorene-acetylene-cyclophane (PPE-type), and ethylene-fluorene-ethylene-cyclophane (PPV-type) copolymers, namely, 4-6, was synthesized via a nickel-catalyzed reaction, a palladium-catalyzed Sonagashira reaction, and a Heck coupling, respectively. Unlike in the fluorene-cyclophane copolymer 3, the transannular pi-pi interaction of the cylophane unit in copolymer 4 resulted in a significant blue shift in its emission spectrum compared to a reference polymer, giving it an essentially blue emitting light. By introducing an acetylene or ethylene linker in going from 3 to 5 or 6, the effective conjugation in the polymer backbone due to higher rigidity in coplanarity decreased the effect of the transannular pi-pi interaction. While the PPV-type copolymer 6 still exhibited an appreciable red shift in both absorption and emission with respect to a reference polymer, negligible shifts were observed for copolymer 5.
