TL;DR: A highly selective copper(II) ion fluorescent sensor has been designed based on the UV-visible absorption of a spiropyran derivative coupled with the use of a metal porphyrin operative on the fluorescence inner filter effect, which presents an excellent selectivity for copper ion in comparison with several other heavy or transition metal ions.

TL;DR: It was observed that the spiropyran 1a binds GSH in aqueous solution with high affinity and shows strong fluorescence emission upon binding and can be utilized in vivo as a GSH probe or as a marker to show the level of intracellular GSH.

TL;DR: The combined data from fluorescence titrations and 1H NMR measurements indicate that the new emission of the spirobenzopyran generated by Cu2+ is the result of the metal-induced ring opening and conformation restriction byCu2+ liganding with the opened merocyanine form and the subsequent reduction of the intramolecular charge transfer of the merocianine.

TL;DR: A new spiropyran compound appended with a pendant bis(2-pyridylmethyl)amine was synthesized and used in fluorescent sensing of pyrophosphate ion (PP(i)) in aqueous solution, which shows the fluorescence response is highly selective for PP(i) over other biologically related substrates, especially the structurally similar anions.
