Abstract
Naphthalene based salen type fluorescent chemosensors have been designed and synthesized for the highly selective detection of silver ions by fluorimetry. These probes 1, 2 and 3 sense Ag+ over other cations as fluorescence ‘on-off’ behaviour. A possible mechanism is proposed, where the heavy atom effect of silver ion overcomes the effect of CN isomerization and intramolecular restricted torsional rotation through the CC single bond between the naphathalene and the benzene moieties. These chemosensors are further utilized to detect Ag+ as strip tests and solid supported silica gel material. These results are further supported by the theoretical calculations.
