Abstract
The present invention relates to nanoparticles of π-conjugated polymers. The present invention also relates to an aqueous composition comprising these polymeric nanoparticles, to processes for making the nanoparticles, and to the use of these nanoparticles in the fabrication of electronic devices and components.
Claims20
An aqueous composition comprising a plurality of nanoparticles dispersed in an aqueous medium, wherein:
- (i) the nanoparticles comprise a core formed from one or more non-cross-linked organic π-conjugated polymers;
- (ii) the nanoparticles have a particle size of less than 400 nm;
- and
- (iii) the concentration of the nanoparticles in the aqueous medium is greater than or equal to 12 mM;
- and wherein the non-cross-linked organic π-conjugated polymers are intrinsic semi-conductors that do not comprise any carbon-carbon triple bonds.
Nanoparticles comprising one or more non-cross-linked organic π-conjugated polymers, wherein:
- (i) the nanoparticles are formed from one or more non-cross-linked organic π-conjugated having a solubility in an organic solvent [e.g. chlorobenzene at room temperature] of less than 10 mg/ml;
- and
- (ii) the nanoparticles have a particle size of less than 400 nm.
