Abstract

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
