Tetrapodal receptors for selective fluorescent sensing of AMP: analyte-induced conformational restriction to persuade fluorescence enhancement

An imine linked fluorescent receptor for AMP has been synthesized with both hydrogen bond donor and hydrogen bond acceptor motifs as recognition sites in the design of a receptor. The receptor recognizes AMP selectively over a number of tested anions and biomolecules such as ADP and ATP, as illustrated through fluorescent enhancement.
