“…7 In the HSAB theory, the Fe 3+ center is a hard acid that has weak bonding with Lewis so base (nearly neutral OH ad ). 40,41 The unbalanced binding energy may drive OH ad towards the Ni 3+ center to deliver further oxidation. It is known that Ni favors the adsorption of OH ad species.…”

“…207 Another rhodamine-based turnon sensor RhBEP (124) was designed by Wang and colleagues, which consists of two rhodamine units separated by a pyridiyldicarbonyl moiety. 208 In phosphate-buffered saline (PBS), this probe showed a 75-fold emission enhancement in the presence of ferric ions corresponding to conversion to the ring-opened spiro-form of the rhodamine unit.…”

Although transition metals constitute less than 0.1% of the total mass within a human body, they have a substantial impact on fundamental biological processes across all kingdoms of life. Indeed, these nutrients play crucial roles in the physiological functions of enzymes, with the redox properties of many of these metals being essential to their activity. At the same time, imbalances in transition metal pools can be detrimental to health. Modern analytical techniques are helping to illuminate the workings of metal homeostasis at a molecular and atomic level, their spatial localization in real time, and the implications of metal dysregulation in disease pathogenesis. Fluorescence microscopy has proven to be one of the most promising non-invasive methods for studying metal pools in biological samples. The accuracy and sensitivity of bioimaging experiments are predominantly determined by the fluorescent metal-responsive sensor, highlighting the importance of rational probe design for such measurements. This review covers activity-and binding-based fluorescent metal sensors that have been applied to cellular studies. We focus on the essential redox-active metals: iron, copper, manganese, cobalt, chromium, and nickel. We aim to encourage further targeted efforts in developing innovative approaches to understanding the biological chemistry of redox-active metals. CONTENTS5908 8.2.

“…Metal ions are known to catalyze the hydrolysis of the imine bond of chemosensors on few occasions and to control their uorescence properties. [41][42][43] The imine bond in HL-CIN is broken in the presence of Group 13 metal ions and a spirocyclic ring opened species (L 2 ) is generated to impart the color change and strong uorescence.…”
