摘要: 四硫富瓦烯及其衍生物是性能优良的电子给体.本文利用Sonogashira反应将吡啶基团连接在四硫富瓦烯单元上,合成了“A-C≡C-TTF-C≡C-A”型四硫富瓦烯共轭体系衍生物4,4’(5’)-二-(4-吡啶乙炔基)-四硫富瓦烯(TTF4N).吸收光谱、电化学和Pb2+配位键合研究表明,三键作为桥基能够有效实现分子内的电荷转移.金属Pb2+离子与吡啶基团的配位能够引起TTF4N的吸收光谱、核磁氢谱和电化学性质的显著变化.

Abstract: Owing to unique π electron-donating-properties,tetrathiafulvalene(TTF) and its derivatives have been extensively studied over the past decade.In the present work,tetrathiafulvalene acetylene derivative [A-C≡C-TTF-C≡C-A],4,4’(5’)-bis(4-pyridylethynyl)tetrathiafulvalene (TTF4N),has been synthesized to provide insight into the nature of the donor-acceptor interaction via triple bonds.Spectroscopic,electrochemical and Pb2+-binding studies demonstrate that the TTF unit interacts with electron-accepting pyridine groups via triple bonds,thus leading to intramolecular charge transfer.Moreover,TTF4N show remarkable sensing and coordinating properties toward Pb2+.

Key words: tetrathiafulvalene, intramolecular charge transfer, coordination interaction
