Microporous microspheres can be used as functional nanomaterial carriers for their microporous structure and higher specific surface area. In this study, magnetic fluorescent polymer microspheres were prepared by incorporating Fe3O4 nanoparticles and CdSe/ZnS quantum dots(QDs) into hyper-crosslinked microporous polymer microspheres(HCMPs) via the in situ coprecipitation method and swelling-diffusion. The HCMPs predominantly have micropores, and their specific surface area is as high as 703.4 m2/g. The magnetic-fluorescent microspheres maintain the superparamagnetic behavior of Fe3O4, and the saturation magnetization reaches 38.6 A·m2/kg. Moreover, the composite microspheres exhibit an intense emission peak at 530 nm and achieve good fluorescence.
