新型银配位聚合物的合成、结构及其光学性质(英文)

Synthesis,structure and optical property of a novel silver(Ⅰ) coordination polymer

报道合成一种新型的带有正电荷的一维链状聚合物并对其结构进行表征.结果显示,分子间的π-π堆积作用增强了体系的稳定性,同时吡啶氮原子与NO3-中的氧形成了经典氢键.文中还通过红外以及单光子荧光对其结构和性质进行了讨论,并对配位后聚合物的荧光猝灭进行了合理解释.

In this paper, a synthesis and the structural characterization of one- dimensional cationic coordination polymeric network were reported. The system was stabilized by off-set face-to-face π-π interactions. In this complex, there were classic intermolecular hydrogen bondings between pyridyl protons and the oxygen atoms of NO3^- anions. Additionally, the results of IR spectra and single-photon excited fluorescence （SPEF） analysis of the structure and property were given and discussed. A fluorescence quenching phenomenon of the coordinated polymer was also found and reasonably explained.
