摘要

The prospective research of non-traditional materials possessing both good electrical and mechanical properties is an interesting aspect of molecular engineering. The various examples presented above well demonstrate that it is possible to fabricate in a quite simple way numbers of organic composites with adaptable conducting properties, by means of a mechanochemical charge-transfer reaction realizable directly in the solid state between two components: an electron donor and an electron acceptor. Crystalline organic metals and superconductors cannot commonly be used in potential applications because of their poor mechanical properties and small dimensions. This is somewhat the same problem with the most interesting new high temperature superconductors like YBaCuO. In the case of organic materials, one way to overcome these inconveniences is then to develop the fabrication of conducting composites by the promising method of solid-solid charge-transfer reactions. Obtention of metallic properties together with good mechanical and chemical stabilities render these materials rather attractive. In the best cases these new composite materials exhibit electrical properties which are not very far from those of the corresponding single crystals, when they exist. Another great advantage of the mechanochemical method is also that new composites can even be fabricated by the same technique, which have no single crystal equivalents.
