Synthesis of a post-modified covalent organic framework as a “turn-on” fluorescent chemosensor for highly selective and sensitive quantitative detection of common trivalent metal ions
Key Points
Detection of trivalent cations is achieved with a new fluorescent chemosensor, improving sensitivity and selectivity.
The chemosensor is capable of quantitatively detecting multiple trivalent cations like Al3+, Ga3+, and Fe3+ with high reliability.
Assessment using synthesized covalent organic frameworks enhanced the chemosensor's fluorescent properties significantly.
These findings highlight the potential for using this technology in various environmental and industrial applications.
Abstract
The selective and ultrasensitive detection of common trivalent cations (Al 3+ , Ga 3+ , In 3+ , Cr 3+ , and Fe 3+ ) using a single fluorophore is an attractive prospect.
