Electrical and Magnetic Properties of Phthalocyanine Iodine Charge Transfer Complex

Abstract

Electrical conductivity and electron spin resonance of the metal free phthalocyanine doped with iodine were investigated.
The electrical resistivity and its activation energy of the phthalocyanine doped with iodine were largely decreased as compared with the undoped metal free phthalocyanine.
The change of the conductivity is attributed to the change of the activation energy. The activation energy of the doped phthalocyanine E is expressed by E=I−2P, where I is the ionization energy and P the polarization energy.
The phthalocyanine doped with iodine showed the strong electron spin resonance absorption at g=2.0036 with the line width of 5.03 gauss and its spin density D varied with temperature according to the following relation
