Enantiomer-selective sensing and the light response of chiral molecules coated with a persistent luminescent material?
Chemical Communications Pub Date: 2019-10-07 DOI: 10.1039/C9CC06014F
Abstract
Pr3+:CaTiO3, a robust persistent luminescent material, was coupled with chiral molecules and Ag nanoparticles (NPs) to construct a Pr3+:CaTiO3@Ag@L-cysteine ternary material that can realize rapid enantiomer selective sensing of L- and D-arginine by making use of the chiral induced spin selectivity (CISS) effect. In addition, long-lifetime photoelectrons excited in the Pr3+:CaTiO3 matrix were effectively transported through a Ag NP “bridge” into the L-cysteine chiral monolayer, due to cooperation between each component in the ternary material.
