Molecular arrangement with a structural configuration and use thereof for quantum-mechanical information processing

摘要

While physically cage-type molecules differ significantly, they are of great chemical similarity so that thus far they cannot be arranged in controllable structures with respect to each other. By contrast, in accordance with the invention, molecular arrangements of geometrically uniform, even periodic, structural configurations of highly precise selectable spacings and angles can be realized in a self-organizing manner by chemically modifying the molecular cages by selective connection of addends. To this end, suitable pairs of types (P') of addends (A', B') which are complementary and selective relative to each other are being used. These usually bilaterally bondable addends (A', B') are at one end bonded to defined selectable positions of the cage molecules (A, B) and form adducts (A2, B2) therewith. The other end is structured to be chemically highly selective so that the addends (A', B') only connect to each other by the chemical lock and key principle. Using stable endohedral fullerenes (Z@Cx with X=60) as cage-type molecules which are filled with an electronspin-supporting atom (Z), it is possible to realize spatially highly precisely arranged electronspin systems for spin quantum computing which by the application of electron spin resonance have a very high detection sensitivity.
