    Conjugated copolymers (CCPs) are a class of polymers with excellent optical luminescent and electrical conducting properties because of their extensive π conjugation. CCPs have several advantages such as facile synthesis, structural tailorability, processability, and ease of device fabrication by compatible solvents.   Electronic and optical properties of conjugated polymers by W. Barford, , Clarendon Press edition, in English.

      A natural solution is to add pendant groups onto the polymer backbone, thus converting CPs into conjugated polyelectrolytes (CPEs). 23, 24 Alternatively, CPs can be made into nanoparticles stabilized with amphiphilic surfactants or block copolymers. 25, 26 Indeed, a majority of the in vivo applications of CPs reported so far are designed around. Nonlinear optics (NLO) is the branch of optics that describes the behaviour of light in nonlinear media, that is, media in which the polarization density P responds non-linearly to the electric field E of the light. The non-linearity is typically observed only at very high light intensities (values of atomic electric fields, typically 10 8 V/m) such as those provided by lasers.

[W Barford] -- Conjugated polymers have important technological applications including solar cells and light emitting devices. They are active components in many important biological processes. This book describes. Rapid growth in biological applications of nanomaterials brings about pressing needs for exploring nanomaterial-cell interactions. Cationic blue-emissive and anionic green-emissive conjugated polymers are applied as dual-color fluorescence probes to the surface of negatively charged magnetic nanoparticles through sequentially electrostatic adsorption.

Optical probes of pristine and Cdoped silicon-bridged PT polymer: a novel highly luminescent low-bandgap polymer Author(s): Martin Liess; Z. Valy Vardeny; W. Chen; Thomas J. Barton. Conjugated polymers (CPs) have been demonstrated as highly sensitive optical probes for protein biosensing. Compared to small molecules, the polymeric probe has the possibility of multiple interactions and a collective response, which enhances the sensor by: Conjugated polymer nanoparticles (CPNs) have emerged as highly photostable probes for optical and photoacoustic imaging.
