摘要：
Ethylenedioxytetrathiafulvalene substituted with a pyridinyl (Py) group (1) shows remarkable sensing and coordinating properties only to Zn2+ ion, not to the other metal ions. Addition of a micromolar concentration of Zn2+ ion to the solution of 1, a dramatic change is observed in the UVvis absorption spectrum and redox property, and the discrimination is readily possible even by the naked eye. Comparison of the recognition ability between 1 and its reference compound (ethynylpyridinyltetrathiafulvalene) 2 suggests that the nature of the space linking tetrathiafulvalene and acceptor moiety plays an important role in the intramolecular charge-transfer state.
