采用非共价键自组装法，将羟基功能化的对苯乙炔基寡聚物（OHOPEL）与水溶性高分子（PEG、PAA和PG）复合，制备了水溶性发光纳米粒子。通过动态光散射（DLS）、紫外光谱和荧光光谱研究了它们的结构和光电性能。OHOPEL基水溶性纳米粒子的光学性质与OHOPEL膜的光学性质相同，表明OHOPEL在纳米粒子中存在链间π-聚集。由共轭低聚物制备的基于OHOPEL的纳米颗粒显示出比由共轭聚合物制备的纳米颗粒更小的尺寸和更低的分散性，这意味着水溶性纳米颗粒的结构与共轭长度相关。此外，OHOPEL/PG和OHOPEL/PAA体系比OHOPEL/PEG体系制备的纳米颗粒更小，多分散性更低，表明非共价键的强度可能对纳米颗粒的尺寸和分散度有影响。
Water-soluble light-emitting nanoparticles were prepared from hydroxyl group functionalized oligos(p-phenyleneethynylene) (OHOPEL) and water-soluble polymers (PEG, PAA, and PG) by non-covalent bond self-assembly. Their structure and optoelectronic properties were investigated through dynamic light scattering (DLS), UV and PL spectroscopy. The optical properties of OHOPEL-based water-soluble nanoparticles exhibited the same properties as that found in OHOPELfilms, indicating the existence of interchain π-aggregation of OHOPELs in the nanoparticles. OHOPEL-based nanoparticles prepared from conjugated oligomers show smaller size and lower dispersity than nanoparticles from conjugated polymers, which means that the structures of water-soluble nanoparticles are linked to the conjugated length. Furthermore, the OHOPEL/PG and OHOPEL/PAA systems produced smaller particles and lower polydispersity than the OHOPEL/PEG system, indicating that there may exist influence of the strength of non-covalent bonds on the size and degree of dispersity of the nanoparticles.
