摘　　要：Iodine-doped (C22H16N2SO2) was prepared by doping the dye with iodine vapor. The following characteristics were obtained by structure analysis.1. The doped iodine exists as I3-anion and I2.2. Because the electron located on the sulphur atom was transferred to iodine, a charge transfer complx of (C22H16N2SO2I5) was formed.3. The complex was proved to exist in a quasi-one dimension conductor state, forming two ordered molecular stacks.4. From the volt-ampere curve with sandwich cell, the room temperature resistivity (ρ)and the exciting energe (ΔE) of the doped complex were shown to he 3.47×107Ω·cm-1and 0.4eV respectivily.5. Its electrical behavior obeys the fomula ρ = ρ0exp(ΔE/kt), showing the behavior of a typical semicanductor.Iodine-doped (C22H16N2SO2) was prepared by doping the dye with iodine vapor.
