摘要： 双酞菁稀土配合物具有夹心式结构,电导率较高,在有机半导体中有广阔的应用前景。作者曾测试了双酞菁稀土在酸性及碱性气氛中的电导率[1],发现其电阻率变化较大。用碘掺杂后电导率提高[2]。Yamana等测得双酞菁钕在氢气和空气中的电阻率分别为1.1ΜΩ·cm和1.9ΚΩ·cm[3],认为双酞菁钕在空气中的低电阻率是吸附氧的缘故。但双酞菁镥在空气、真空及氢气中的电阻率均为0.12MΩ·cm(250℃)[4]。本文研究双酞善稀土在不同气氛中的导电特性。

Abstract: Diphthalocyanine erbium complex has been proved to be of a sandwich structure by x-ray diffraction spectrum,and ultraviolet and infraed spectrophotometry. The volt-ampere curve and the risistivity-temperatrue curve under different atmosphere showed its activation energy(ΔE) was 0.278eV in vacuum and 0.274eV in oxygen. Under diffrent atmosphere, the resistivity is 1.16(H2), 1.14(vaeuum),1.03(N2), 0.88(air), 0.86(O2)ΜΩcm. It is showed that the conductive property of [Pc2Er]H is due to the extrinsic impurity conduction.

Key words: diphthalocyanine erbium, conductivity, organic semiconductor
