Abstract

The fluorescence excimer emission of 1 is found to be enhanced upon the addition of K+ ion which is due to a conformational change of the ligand to have a more efficient -* interaction of two pyrenes. By contrast, no fluorescence change of 1 was observed in the anion binding test with F-, Cl-, Br-, I-, [image omitted], [image omitted], and [image omitted] as their tetrabutylammonium salts in MeCN. Interestingly, it was observed that the excimer emission of the two pyrenes decreases upon the addition of [image omitted] or [image omitted] in the 1K+ complex solution. This is presumably due to a conformational change of the ligand by K+ ion binding, which induces the better conformation of two facing pyrene amides to selectively adopt [image omitted] or [image omitted] ion. This allosterical anion complexation could be applicable for NOR and INHIBIT (INH) logic gates.
