Enabling single qubit addressability in a molecular semiconductor comprising gold-supported organic radicals.

ABSTRACT: A bis(dithiolene)gold complex is presented as a model for an organic molecular electron spin qubit attached to a metallic surface that acts as a conduit to electrically address the qubit. A two-membered electron transfer series is developed of the formula [Au^III(adt)₂]^1-/0, where adt is a redox-active dithiolene ligand that is sequentially oxidized as the series is traversed while the central metal ion remains Au^III and steadfastly square planar. One-electron oxidation of diamagnetic [Au^III(adt)₂]^1- (1) produces an S = 1/2 charge-neutral complex, [Au^III(adt₂ ^3-˙)] (2) which is spectroscopically and theoretically characterized with a near negligible Au contribut
