Magnetic polymer particles with hydro groups on the surface were synthesized by disperse polymerization in the presence of magnetic fluid

then a novel kind of green magnetic polymer particles (PSFePc(COOH)3) was obtained by bonding the magnetic polymer particles with phthlaocyanine．The structure and properties of PSFePc-(COOH)3 particles were identified by infrared spectroscopy

element analysis and scanning electron microscopy etc．It was found that：(1) the particle size is in the range of l0～100 μm and the grafting ratio of phthlaocyanine is about 4.8％；(2) the particles show a good magnetic response in magnetic field

it takes about 2 h in natural sedimentation to reach a transmittance of 95％

while the same separation results under a magnetic field of 0.42T only need about 10 min；(3) the particles have photoconductivity．It maybe helpful to find a new method for detecting the interaction between bio-active molecules by using photoconduetivity measurements．
