Project

One of the major interests of modern chemistry is molecular electronics. Many efforts have been made to construct electronic devices from a single molecule since the first demonstration that this could be done with polyconjugated systems. However, it can be foreseen that this strategy suffers from a tremendous handicap: the reliability of the whole device depends on one unique and often fragile molecule. Less risky is adoption of a strategy between the two extremes of silicon based electronics, relying on billions of atoms and therefore tolerating some local defects, and single molecule based electronics highly sensitive to a defect. A system based on a small number of molecules or better "conducting groups" can furnish a compromise. This approach is illustrated by the use of charge transporting liquid crystals already in use in some commercial OLEDs. But the liquid crystals studied so far have little electron affinity, and are hole carriers.
This project aims at synthesising and studying conducting, selfassembled liquid crystals with a high affinity for electrons. The conducting properties will take advantage of the 1,1,4,4-tetracyanobuatdiene chemistry that has been developed to build cores able of reversible oxidation/reduction steps. They will be decorated with a cyanuric acid motif. Melamine assemblers should maintain them closely packed into column permitting the hopping of the electrons, and bear the decoration that will provide the liquid crystal properties, as well as insulation of the conducting column. The supramolecular approach will enhance the versatility of the core synthesis, permit reticulation or further postmodification, and self repair. On a wider scale, what is looked for here is the integration of two molecular functions -electron affinity and self assembly- into a more complex architecture to create functional wires and networks with possible application in nanoelectronics.
