σ-单键连接的TTF吡啶衍生物对Pb2+的识别

摘要

设计合成了一类σ-单键连接的TTF吡啶化合物T4Py和TB,并研究了化合物T4Py对离子的识别作用.结果发现Pb2+离子能够引起T4Py的溶液颜色、1HNMR以及电化学CV的显著变化.%Two σ-bridged TTF-σ-pyridine derivatives, T4Py, and TB, were synthesized and characterized. It was found that T4Py displayed remarkable changes in solution, 1 HNMR spectra, and electrochemical properties, upon complexation with Pb2+ ions.
