Colloidal CdSe nanocrystals passivated by a dye-labeled multidentate polymer: Quantitative analysis using size exclusion chromatography

Mingfeng Wang, Tieneke E. Dykstra, Xudong Lou, Mayrose R. Salvador, Gregory D. Scholes, and Mitchell A. Winnik

Angew. Chem. Int. Ed. Eng. 45, 2221–2224 (2006).

Hold on tight: Pyrene-labeled poly(dimethylaminoethyl methacrylate) (Pyr-PDMAEAMA) was synthesized as a multidentate ligand for CdSe nanocrystals (NCs, see picture). The mean number of polymers that bind to each NC can be determined by a quantitative analytical method based on size-exclusion chromatography. Spectroscopic characterization of the eluted particles shows that Pyr-PDMAEAMA binds tightly to these NCs.
