英文摘要A series of tetrathiafulvalene acetylene derivatives, [ttf-cc-a] [a = c6h4n(ch3)(2)-4 (1), c6h4och3-4 (2), c6h5 (3), c6h4f-4 (4), c6h4no2-4 (5), c5h4n-2 (6), c5h4n-3 (7), and c5h4n-4 (8)], have been designed and synthesized to provide insight into the nature of the donor-acceptor interaction via a pi-conjugated triple bond. the x-ray crystal structure of [ttf-(cc)-c6h4och3-4] (2) reveals that the phenyl ring linked by acetylene is almost coplanar to the plane of ttf with a dihedral angle of 3.6 degrees. the strong intermolecular c-h center dot center dot center dot o hydrogen bonding was found to direct the molecular helical assemblies with a screw pitch of 5.148 angstrom when viewed along the a-axis. spectroscopic and electrochemical behaviors of the tetrathiafulvalene acetylene derivatives demonstrate that the ttf unit interacts with the electron-accepting group through the triple bond, thus leading to the intramolecular charge transfer. the pyridine-substituted ttf compounds 6-8 show remarkable sensing and coordinating properties toward pb2+. comparison of the spectroscopic and electrochemical properties and the calculation at the b3lyp/6-31g* level available in gaussian 03 reveals that varying the bridged unit of the ttf-pi-a system from a double bond to a triple bond leads to positive shifts for the first and second oxidation potentials of the ttf moieties, while the extent of intramolecular charge transfer interactions through the pi-conjugated triple bond is smaller than that through the double bond.
