The present report describes the preparation of lanthanide-doped colorless magnetic materials based on poly-beta-ketoester particles. Monodisperse poly(2-acetoacetoxy ethyl methacrylate) (PAAEM) particles were prepared by dispersion polymerization using AAEM as the monomer in the presence of a cross-linker. Because of the swelling characteristics of the cross-linked PAAEM particles in solvent, the lanthanide was effectively doped inside the particles, and the distribution of the lanthanides in the particles was visualized. By creating terbium (Tb)-doped PAAEM particles (PAAEM/Tb), which has luminescence properties in addition to magnetic properties, the relationship between efficient lanthanide doping conditions and magnetism was clarified. Because of the low coloration of lanthanides, the resulting PAAEM/Tb particles were colorless magnetic materials compared with conventional iron oxide magnetic nanoparticles. Magnetic force microscope measurements revealed that each particle exhibited magnetism. In addition, because of the high dispersibility of PAAEM/Tb particles and their colorless nature, the inkjet printing of particles and preparation of composites with commodity polymers have been demonstrated. The present technique has been shown to be widely applicable to other lanthanides instead of Tb. This versatile process enables the development of colorless functional polymeric materials with magnetic properties.
