Preparation and sensing performance of chiral carbon Dot@MOF electrode material

Abstract

Chirality is a ubiquitous phenomenon in nature. The identification of chiral compounds has important theoretical significance and application prospects in many fields such as biology, medicine, and food. This paper proposes an innovative approach to differentiate enantiomers by using the synergistic effect of chiral MOFs and CDs through electrochemiluminescence. The results demonstrate that CDs@[Zn(D-cam)(phen)(H2O)]n exhibit higher electrochemiluminescent response towards L/D-Trp, enabling the detection of Trp enantiomers. This research suggests that selective recognition of amino acid enantiomers can be achieved through ECL-based nanocomposites of CDs and porous MOFs.
