Iron(III) selective molecular and supramolecular fluorescent probes
TL;DR: Attempts have been made to review the various molecular and supramolecular fluorescent sensors that have been developed for the selective detection of iron(III) to provide online monitoring of very low concentrations without any pre-treatment of the sample together with the advantages of spatial and temporal resolution.

Single- and Multiphoton Turn-On Fluorescent Fe3+ Sensors Based on Bis(rhodamine)
TL;DR: High selectivity and sensitivity is observed over other metal ions and is shown to be due mainly to the spirolactam ring-opening power of Fe(3+).

A fluorescent chemical sensor for Fe3+ based on blocking of intramolecular proton transfer of a quinazolinone derivative.
TL;DR: 2-(2'-hydroxy-phenyl)-4(3H)-quinazolinone (HPQ), a typical compound that exhibits excited state intramolecular proton transfer (ESIPT) reaction and possesses good photophysical properties, is synthesized and used as fluoroionophore for Fe(3+) sensitive optochemical sensor.
