Heterometallic Rings Made From Chromium Stick Together Easily

摘要

The idea that coordination complexes could be used in quantum information processing (QIP) was introduced by Leuenberger and Loss, and later developed by them and others. Our contribution has been to look at the S = 1/2 ground state {Cr7Ni} anti-ferromagnetically coupled rings, including measuring spin coherence times. For QIP to work there is a need to link such rings into more sophisticated structures; we have previously reported such a chemical link via an amine-template, but in that link there was no exchange interaction between the two {Cr7Ni} rings in the structure. Therefore we have looked for new methods to link such rings.
