Abstract
We report the template assembly of luminescent poly-3-hydroxybutyrate (PHB) particles doped with rare-earth complexes. The hydrophobic polymer, PHB, has been infiltrated into the nanopores of mesoporous silica (MS) particles in organic solvent. Because of the van der Waals interaction of the polymer chains, PHB loaded in the nanopores yields replicated particles following removal of the MS template. To prevent aggregation of the hydrophobic PHB particles in aqueous media, the PHBloaded mesoporous silica particles were coated with a polyelectrolyte multilayer (PEM) shell through the layer-by-layer (LbL) assembly of poly(allylamine hydrochloride) (PAH) and poly(sodium 4-styrenesulfonate) (PSS)..
