A Noncovalently Reversible Paramagnetic Switch in Water
We
report an organo-paramagnetic switch consisting of a linked
bisÂ(viologen) dication diradical that can be cycled reversibly between
diamagnetic and paramagnetic states via noncovalent guest–host
chemistry with cucurbit[7]Âuril (CB[7]) in room-temperature water.
Computations suggest that the nature of the interaction between the
viologen cation radical units is that of a pi dimer (pimer). Molecules
with switchable magnetic properties have possible applications in
spintronics, data storage devices, chemical sensors, building blocks
for materials with switchable bulk magnetic properties, as well as
magnetic resonance probes for biological applications
