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 (△E) of the doped complex were shown to be 3.47×107Ω•cm-1 and 0.4eV respectively.
5.Its electrical behavior obeys the fomulaρ=ρoexp(△E/kt),showing the behavior of a typical semiconductor.
- Iodine-doped,
- Multiplex charge transfer complex,
- Quasi-one dimension conductor
