A light controlled, sensitive, selective and portable spiropyran based receptor for mercury ions in aqueous solution

[Display omitted] •A benzothiazolinic spiropyran was synthesized with subsitutent at a unique position to bind metal ions.•The structure of the spiropyran derivative was established through x-ray crystallography.•The spiropyran derivative selectively detected highly toxic Hg2+ ions in aqueous soluti...
