Pyridinium-based symmetrical diamides as chemosensors in visual sensing of citrate through indicator displacement assay (IDA) and gel formation

Abstract

The design and synthesis of pyridinium-based symmetrical diamides 1 and 2 along with their anion binding studies through ‘indicator-diplacement assay’ are reported. Both the chemosensors effectively respond in in CH3CN–H2O (4 : 1 v/v) at pH = 6.3 for the selective naked-eye detection of citrate. Additionally, chemosensor 2 (c = 6.29 × 10−3 M) forms a stable gel only with citrate in CH3CN, which validates its visual sensing.
