Guest-responsive coherence time of radical qubits in a metal–organic framework

Abstract

Metal–organic frameworks (MOFs) integrated with molecular qubits are promising for quantum sensing. In this study, a new UiO-type MOF with a 5,12-diazatetracene (DAT)-containing ligand is synthesized, and the radicals generated in the MOF exhibit high stability and a relatively long coherence time (T₂) responsive to the introduction of various guest molecules.
