One-dimensional (1D) magnetic fluorescent Fe3O4/P(GMA-EGDMA-NVCz) peapod-like nanochains have been successfully synthesized by magnetic-field-induced distillation precipitation polymerization. Fe3O4 microspheres can be arranged with the direction of external magnetic field in a line via the dipolar interaction between Fe3O4 microspheres and linked permanently via P(GMA-EGDMA-NVCz) coating during distillation precipitation polymerization. Magnetic measurement revealed that these 1D peapod-like nanochains showed highly magnetic sensitivity. 1D magnetic nanochains can be oriented and aligned along the direction of external magnetic field. The length of peapod-like nanochains can be controlled by magnetic field intensity. The shell thickness and fluorescent intensity can be adjusted by the amount of monomers.
