| Research Abstract |
Supramolecular techniques such as host-guest complex formation have been used to tune molecule-based magnetic materials. We have developed several magnetic materials possessing nano-sized pores or cavities, whose magnetic properties were changed by inclusion of small diamagnetic molecules. Some magnetic materials exhibited photo-induced magnetism. We also developed single-molecule magnets containing 3d-and 4f-metal ions. Several results from this project are listed below :
1)Weak ferromagnet possessing a chiral lattice was prepared and their magnetic structure was characterized by means of polarized neutron diffraction study.
2)Photo-induced magnetism was found in [M(pm)(N_3)_2](M=Mn,Fe,Co,Ni).
3)Diamagnetic-ion inclusion was applied for the magnetic coupling switch in the nickel(II) complex having a polyether side-arm.
4)Crown-ether spin label reagents were developed.
5)Honeycomb-like porous compound [Cu(4APM)(OCH_3)(NO_3)] was prepared and the crystal structure was solved in a relatively rare space group R-3.
6)The high-spin ground state was characterized for the hybrid metal-radical solid [Ni(4ImNNH)_2(NO_3)_2].
7)The lanthanide-containing complexes [DyCuDy],[Dy_4Cu], and [Tb_4Cu] behaved as single-molecule magnets.
