摘要

Polycarbazole has been synthesiszed by electrochemistry.The carbazole monomer source consists either in carbfazole in solution in the electrolyte or in carbaole deposited in thin film form onto the working electrode. The two families of polymers have been studied by infrared absorption, X-ray diffraction,thermal gravimetric analysis, scanning electrn microscopy (SEM),X-ray photoelectron spectroscopy,electron spin resonance,and electrical conductivity measurements.It is shown that the polycarbazole films obtained with carbazole deposited in the thin film form exhibit a better polymerization efficiency and an electrical conductivity one order of magnitude higher.This result is in good accordance with a higher spin desity ad homogeeity.It is proposed that not only are some monomers activated during the evaporation but also that the physical contact between the working electrode and the continiuous carbazole films induces the growth of homogenous highly polymerized polycarbazole films.In agreement with this suggestion, the SEM study shows that this type of polycarbazole thin films keep in memory the morphology of the SnO_2 under layer.
