TLDR
A selective and sensitive fluorescent chemosensor for Hg2+, which was composed of two aminonaphthalimide fluorophores and a receptor of 2,6-bis(aminomethyl)pyridine, showed an about 17-fold increase in fluorescence quantum yield upon addition of 1 equiv of HG2+ in neutral buffer aqueous solution.Abstract:
A selective and sensitive fluorescent chemosensor for Hg2+, which was composed of two aminonaphthalimide fluorophores and a receptor of 2,6-bis(aminomethyl)pyridine, was synthesized through the reaction of 2,6-bis(chloromethyl)pyridine and N-[2-(2-hydroxyethoxy)ethyl]-4-piperazino-1,8-naphthalimide. The chemosensor showed an about 17-fold increase in fluorescence quantum yield upon addition of 1 equiv of Hg2+ in neutral buffer aqueous solution, and the other common metal ions did not notably disturb the detection of Hg2+.read more

Design principles of fluorescent molecular sensors for cation recognition
TL;DR: The main classes of fluorescent molecular sensors for cation recognition are presented: they differ by the nature of the cation-controlled photoinduced processes: photoinduced electron transfer, photoinduced charge transfer, excimer formation or disappearance as discussed by the authors.

Fluorescent Chemosensors for Cu2+ Ions: Fast, Selective, and Highly Sensitive.
TL;DR: Low cross-sensitivity for other metal ions and the ability to detect nanomolar concentrations of Cu2+ ions are the exciting properties of fluorescence sensors in which a fluorophore and a chelating group are discrete subunits of the same molecule.
