The use of 4-substituted pyridines to afford amphiphilic, pegylated cadmium selenide nanoparticles

Amphiphilic cadmium selenide (CdSe) nanoparticles were prepared by surface functionalization with novel ligands 1 and 2, composed of pyridine moieties substituted in the 4-position with polyethylene glycol (PEG) chains.
