Abstract

A new water-soluble and fluorescent imidazollum-anthracene cyclophane (1) effectively recognizes the biologically Important GTP and I- over other anions in a 100% aqueous solution of physiological pH 7.4. Fluorescence and H-1 NMR spectra and ab initio calculations demonstrate that emission arises from the formation of an excimer state and quenching occurs upon GTP/I- binding through (C-H)(+)center dot center dot center dot A(-) hydrogen bond interactions.
