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,发现其电阻率变化较大。用碘掺杂后电导率提高。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,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、
Diphthalocyanine erbium complex has been proved to be of a sandwich structure by xray 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(H_2), 1.14(vaeuum),1.03(N_2), 0.88(air), 0.86(O_2)ΜΩcm. It is showed that the conductive property of [Pc_2Er]H is due to the extrinsic impurity conduction.
