Ion-responsive fluorescent compounds
TLDR
In this article, the complexation ability of coumarin 153 linked to monoaza-15-crown-5 was studied and the stability of the complexes remains high enough in acetonitrile-water mixtures for practical application to the determination of cation concentrations in aqueous samples.About:

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.

TL;DR: Fluorescent PET (photoinduced electron transfer) sensors are considered to be those molecular systems where the binding of ions and other species leads to the perturbation of the competition between the deexcitation pathways of fluorescence and electron transfer.

On the (uninteresting) dependence of the absorption and emission transition moments of coumarin 153 on solvent
TL;DR: In this paper, the absorption and emission transition moments of coumarin 153 as well as fluorescence lifetimes and quantum yields were measured over a broad range of solvents in which the emission and absorption frequencies varied substantially.

Chalcone-Analogue Dyes Emitting in the Near-Infrared (NIR): Influence of Donor−Acceptor Substitution and Cation Complexation on Their Spectroscopic Properties and X-ray Structure
TL;DR: In this paper, the photophysical properties of newly synthesized 1-benzothiazole-3-(4-donor)-phenyl-substituted prop-2-en-1-ones were studied as a function of solvent polarity, temperature, and metal ion by employing steady-state and time-resolved spectroscopy.

A new generation of Ca2+ indicators with greatly improved fluorescence properties.
TL;DR: A new family of highly fluorescent indicators has been synthesized for biochemical studies of the physiological role of cytosolic free Ca2+ using an 8-coordinate tetracarboxylate chelating site with stilbene chromophores that offer up to 30-fold brighter fluorescence.

Fluorescent crown ether reagent for alkali and alkaline earth metal ions
TL;DR: In this paper, N-(4-methylumbelliferone-8-methylene)-monoaza-15crown-5 (1) and -18-crown6 (2) extract most efficiently lithium and potassium, respectively, from aqueous solution to 1,2-dichloroethane.
