Abstract

Polyamidoamine PAMAM dendrimers were used to produce CdSe core/multishell fluorescent quantum dots QDs which are colloidally stable in aqueous solutions The size charge and optical properties of QDs functionalized with the 4th G4 and 5th G5 generation of PAMAM were compared with amphiphilic polymercovered QDs and used as criteria for the evaluation of the suitability of both water solubilization methods As revealed by dynamic and electrophoretic light scattering DLS and ELS the hydrodynamic sizes of the QDs varied from 30 to 65 nm depending on QD type and dendrimer generation with all QDs displaying highly positive surface charges ie zeta potentials of around +50 mV in water PAMAM functionalization yielded stable core/multishell QDs with photoluminescence quantum yields Φ of up to 45  These dendrimercovered QDs showed a smaller decrease in their Φ upon phase transfer compared with QDs made water soluble via encapsulation with amphiphilic brush polymer bearing polyoxyethylene/polyoxypropylene chainsThe work was supported by the German Academic Exchange Service Funding Program Number 50015386 the European Commission EMRP project NEW03 NanoChOp EMPIR project JRPi04 Metrology for innovative nanoparticles INNANOPART project 14IND12 QD development and hydrophilization was supported by Russian Science foundation Project 141300229
