✦ Synopsis

Thin films of bisphthalocyaninatolutetium derivatives (Pc*Lu) have been doped using a co-sublimation technique with an electron acceptor (dichlorodicyanoquinodimethane, DDQ) and an electron donor (tetraphenyldithiapyranylidene, DIPSad). The conduction properties of Pc,Lu and of p-and n-type doped materials have been determined and correlated with the optical characteristics of the films. PczLu is the first molecular semiconductor that satisfies the following three criteria: (i) it is a molecular material, (ii) its intrinsic conductivity is in the range 10-6-10-' n-' cm-', (iii) it can be doped with both electron acceptors and electron donors.
