摘要

中性条件下，以二茂铁甲醛和对苯二胺为原料，合成了二茂铁基席夫碱，考查了反应温度和时间对产率的影响，并测得其本征态室温电导率σ＝1.26×10-9 S·cm-1。利用Fe3+、Al3+、Ti3+盐对二茂铁基席夫碱进行了掺杂，探讨了掺杂量和掺杂温度对产物室温电导率的影响，研究了掺杂产物电导率与温度的变化关系，并用红外光谱、紫外光谱和电子探针对产物结构和组成进行了表征。结果表明：经金属盐掺杂后，电导率可提高4～5个数量级，根据Arrhenius曲线得到了化合物的电活化能在0.09～1.54 eV范围内，表明了它们具有较好的半导体性能。

Abstract

Ferrocenyl Schiff base was synthesized with ferrocenecarboxaldehyde and p-phenylenediamine as precursors under neutral condition. The effects of the temperature and time of reaction on the yield were investigated

and the room-temperature electric conductivity of the intrinsic sample was 1.26×10-9 S·cm-1.The doping of ferrocenyl Schiff base with Fe3+

Al3+ and Ti3+ salt

and the effects of the dosage of doping agent and doping temperature on the room-temperature electric conductivity of samples were discussed. In addition

the temperature dependence of electric conductivity of samples were studied

and their structures and compositions were characterized with infrared spectrum

ultraviolet spectrum and electron probe X-ray microanalyser.The results showed that the electric conductivity of the sample could increase 4～5 by orders of magnitude after doping with metallic salt. The electrical activation energies of the complexes in the range of 0.09～1.54 eV were calculated from Arrhenius plots

indicating their favourable semiconducting behavior.
