摘要:
Cage-type molecules differ significantly physically but are so chemically similar that until now it has been impossible to arrange them in relation to each other in controllable structures. According to the invention however, molecular arrangements with geometrically regular, periodic structural configurations with extremely precisely selectable intervals and angles can be produced in a self-organised manner by chemically modifying the molecular cages by specifically applying addends. Suitable type pairs (P') consisting of complementary and selective addends (A', B') are used. These addends (A', B'), which are generally bondable on two sides, are bonded with specific selectable sites of the cage molecules (A', B') with one end and form adducts (A2, B2) with the same. The other end is configured to be chemically highly selective so that the addends (A', B') bind exclusively with each other according to the chemical lock-and-key principle. By using stable, endohedral fullerenes (Z@Cx with X = 60) as cage-type molecules, filled with an electron spin carrying atom (Z), it is possible to produce spatially extremely precisely arranged electron spin systems for spin quantum computing, with very high detection sensitivity due to the use of electron spin resonance.
