Abstract
The designation “molecular semiconductor” has never received any clear cut definition. The following criteria are proposed: (i) it is a molecular material constituted of molecular units which can be individually synthesized (ii) its intrinsic conductivity is in the range 10−6-10−1Ω−1 cm−1 (iii) it can be doped with electron donors and/or electron acceptors to form n-or p-doped materials. This paper deals with the description of the electrical properties of lithium phthalocyanine PcLi and lutetium bisphthalocyanine Pc2Lu, in the intrinsic and extrinsic conduction ranges.Keywords
