Abstract

An alkyne-functionalized ruthenium(II) bis-terpyridine complex is directly copolymerized with phenylacetylene by alkyne polymerization. The polymer is characterized by size-exclusion chromatography (SEC), (1) H NMR spectroscopy, cyclic voltammetry (CV) measurements, and thermal analysis. The photophysical properties of the polymer are studied by UV-vis absorption spectroscopy. In addition, spectro-electrochemical measurements are carried out. Time-resolved luminescence lifetime decay curves show an enhanced lifetime of the metal complex attached to the conjugated polymer backbone compared with the Ru(tpy)2 (2+) model complex.

摘要

一种炔基官能化的钌（II）双三联吡啶配合物通过炔烃聚合与苯乙炔直接共聚。该聚合物通过尺寸排阻色谱（SEC）、（1）H核磁共振光谱、循环伏安法（CV）测量和热分析进行表征。通过紫外可见吸收光谱研究了该聚合物的光物理性质。此外，还进行了光谱电化学测量。时间分辨发光寿命衰减曲线表明，与Ru（tpy）2（2+）模型配合物相比，连接到共轭聚合物主链上的金属配合物的寿命有所延长。
