Photoluminescent Polymer/Quantum Dot Composite Nanoparticles

Farmer, Steven C., Patten, Timothy E.·2001·Chemistry of Materials

Abstract

Core−shell CdS/SiO 2 nanoparticles were prepared and modified with the atom transfer radical polymerization (ATRP) initiator 3-(2-bromopropionyloxy)propyl dimethylethoxysilane (BIDS). The initiator-modified nanoparticles were then used as macroinitiators for the polymerization of methyl methacrylate (MMA) catalyzed by NiBr 2 (PPh 3 ) 2 . These hybrid polymer/inorganic nanoparticles could be cast into films that retained the photoluminescence of the precursor CdS nanoparticles and showed even dispersal of the CdS/SiO 2 cores throughout the PMMA matrix. These hybrid nanoparticles are versatile structures: their films can be processed from solution and show uniform dispersion of the inorganic phase throughout the host organic matrix on the microscopic level. These nanoparticles also have components whose structures and compositions can be altered to introduce new properties to the material (i.e., the luminescence of the inorganic core or the conductivity of the polymer arms) and to allow for self-assembly of the material (via the structure and composition of the polymer arms).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
