초록

A supramolecular complex composed of bis-pyridinium picket calix[4]pyrrole and azophenol indicator is a highly visible colorimetric displacement assay and sensor. The system shows significant selectivity and a higher affinity for pyrophosphate anions over other competing anions. (C) 2013 Elsevier Ltd. All rights reserved.
