Suppression of spin-spin coupling in nitroxyl biradicals by supramolecular host-guest interactions
The use of supramolecular architectures to control the spatially dependent spin exchange (spin communication) between two covalently linked radical centers (biradical) has been explored. Cucurbit[8]uril, through supramolecular steric effect, completely suppresses spin exchange between two adjacent radical centers in a biradical. The Royal Society of Chemistry.
