摘要:
A novel pi-conjugated donor-acceptor compound (1) based on tetrathiafulvalene (TIT), which is functionalized with dipyridine, has been designed and synthesized. Spectroscopic and electrochemical behaviors of compound 1 demonstrate that the donor (TTF) unit strongly interacts with the electron-accepting group through the heteroaromatic bridge. The interaction of compound 1 with metallic ions can cause remarkable changes in the absorption and fluorescence spectra. OFT calculations reveal that the pyrazine ring is almost coplanar with the TTF plane, which is beneficial to the donor and acceptor electronic communication. Additionally, compound 1 can be self-assembled into nanostructures with smooth surface, hecto-nanometers in width and deca-micrometers in length. (C) 2012 Elsevier Ltd. All rights reserved.
