| Popis: | Charge-transfer complex of C 60 with 1,1′-biferrocene(Bifc) was prepared. The charge-transfer property was investigated by infrared and uv/vis/nir spectroscopy. The charge-transfer process was studied in detail by electron paramagnetic resonance spectroscopy. A complex reaction behavior has been observed. Studies of variable temperature EPR in the solid state show g-value shift as well as with peak-width change. A relaxation with degradation process of this charge-transfer complex was proposed. Magnetic studies conducted by SQUID magnetometer show that the magnetic behavior of these charge-transfer complexes could be described as superposition of paramagnetic and ferromagnetic components. The coercive forces and residual magnetizations of these complexes measured at low temperature are discussed. |
