Characterization of amine stabilized CdSe/ZnS core-shell quantum dots by using triarylpyrylium dyes

A new method to study the stabilizing primary amine ligands coordinated to the surface of CdSe/ZnS core-shell quantum dots has been developed. The method is based on the reactivity of fluorescent 2,4,6-triarylpyrylium dyes with the aforementioned ligands to afford non-emissive 2,4,6-triarylpyridiniu...

Zusammenfassung:A new method to study the stabilizing primary amine ligands coordinated to the surface of CdSe/ZnS core-shell quantum dots has been developed. The method is based on the reactivity of fluorescent 2,4,6-triarylpyrylium dyes with the aforementioned ligands to afford non-emissive 2,4,6-triarylpyridinium cations. A new method to study the stabilizing primary amine ligands coordinated to the surface of CdSe/ZnS core-shell quantum dots has been developed.
