Dual-channel recognition of Al³⁺ and Cu²⁺ ions using a chiral pyrene-based fluorescent sensor

Abstract

A chiral cation sensor comprising two pyrene rings and a diethylene glycol linker has been developed and utilized to detect Al3+ and Cu2+ ions based on differences in circular dichroism...

Pyrene Functionalized Luminescent Phenylalanine for Selective Detection of Copper (II) Ions in Aqueous Media

“…[35][36][37][38][39][40] in recent years many study have been done using pyrene derivatives to sense various ions such as Al 3+ , Cu 2+ , Fe 3+ , Cr 3+ . 41,42 Yang et. al develop a pyrene based uorescent sensor for the detection of Cu 2+ ions.…”

In situ construction of a cobalt oxyhydroxide loaded pyrene-based fluorescent organic nanoprobe for bioimaging of endogenous ascorbic acid in living cells

“…12,13 According to their promising photophysical properties, pyrenes or excimers have been regarded as a promising chemosensor for use in detection and imaging applications. [14][15][16][17] Moreover, a series of bispyrenebased self-assembled nanomaterials with different aggregation types and optical properties were successfully constructed via an ''in vivo self-assembly'' strategy in living objects. 18,19 Most of these studies aimed at the preparation, characterization and formation mechanism of pyrene-based FONs (PyFONs), however, research on the construction and application of a sensing platform based on pyrene FON composite materials with inorganic two-dimensional (2D) nanomaterials has been very rare.…”
