Abstract: A series of conjugated polymer/oligomer based water-soluble light-emitting nanoparticles, made by non-covalent bond self-assembly with poly- or oligo(p-phenyleneethynylene) (PPE or OPE) and water-soluble polymers (PAA, PEG, PG), have been prepared and characterized. The OPE-based nanoparticles exhibit a good water-solubility and a low degree of size dispersity, which are highly desired for applications in chemo- and bio-sensors. Furthermore, the results show a strong correlation between strength of hydrogen bonds between the water soluble polymer and the conjugated oligomer, size and degree of dispersity of the nanoparticles. Surprisingly, the formation of the nanoparticles are little influenced by the molecular architecture of conjugated molecules.
