英文摘要	Self-assembly based on spontaneous control of non-covalent interaction, such as van de Waals forces, pi - pi interaction, electrostatic forces, can be applied to the fabrication of structured system at a molecular level. In this paper, binary surfactants (trioctylphosphine oxide and oleic acid) were added when the iron complex Fc(acac)(3) was reduced to Fe nanoparticles by N2H5OH in enthylenediamine with PVP under a solvothermal reaction, resulting in spherical aggregates. The average size of the assembled sphere is about 210 +/- 10 nm. A similar reaction without the surfactants just gave smaller Fe-nanoparticles (ca. 60 nm) without such an aggregation. The magnetic properties of the spherical aggregates were investigated by a superconducting quantum interference device (SQUID) magnetometer. The particles show a bulk-like softmagnetic Fe behavior.; Chemistry, Physical; CPCI-S(ISTP); 0
