| 摘要 | A new series of 9-fluorenone-iodine-alkali iodide complexes (FIMI, M=Na, K, Rb or Cs) has been prepared from chloroform. These complexes yield needle-like crystals with metalic luster along the needle axis. The longitudinal dc conductivities at room temperature are in the order of 10/sup -3/to 10/sup -5/ S cm/sup -1/. They all have semiconductive properties with activation energies of about 0.4 to 0.7 eV. A significant result is that the conductivity varies systematically with the cation size. A decrease in the cation results in an increase in the conductivity. Resonance Raman spectra show that iodine is present as a linear chain of symmetric I/sub 3//sup -/ units in these complexes. Infrared spectra of these complexes are discussed with an attempt to estimate the interaction between the alkali cation and the carbonyl group of 9-fluorenone. |
