Abstract
Abstract The quenching of fluorescence intensity and decay time of protonated form of 6-methoxyquinoline (6MQ + ) with chloride ion (Cl − ) in aqueous solution at ambient temperatures have been investigated. The quenching follows linear Stern–Volmer relation. The values of Stern–Volmer quenching constant/quenching efficiency ( K sv ) and quenching rate constant ( K q ) for the Cl − ion are close to 75 M −1 and 3.21×10 9 M −1 S −1 , respectively. The quenching is found to be collisional or dynamical in nature. The study reveals that the system can be used as a sensor for the detection of chloride ion.
