Among various approaches, the qubits based on paramagnetic centers have decent advantages, including their diversity and possibilities of regular ordering, for example, within the structure of metal-organic frameworks (MOFs). In the present work a simple and scalable approach to obtain qubit candidates based on stable organic radical 3-carboxy-proxyl and MOF-808 framework has been demonstrated. Investigation of the obtained compounds with different radical amounts using electron paramagnetic resonance (EPR) demonstrates the presence of two fractions of radicals, which is supported by simulations. Sufficiently long phase memory time at room temperature for the radicals adsorbed into MOF (0.39 μs), as well as the observed Rabi nutations, allow considering this material as a platform for qubits design. The developed approach is capable of incorporating various amounts of paramagnetic centers into the MOF structure and can be employed to obtain other spin qubit candidates.","PeriodicalId":759,"journal":{"name":"Russian Journal of Coordination Chemistry","volume":"50 9","pages":"646 - 652"},"PeriodicalIF":1.1,"publicationDate":"2024-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1134/S1070328424600335.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142790287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The photoluminescence properties of the obtained complexes (I–III) were studied in the solid state and in solution. In the absorption spectra of the complexes, a charge transfer band is observed at 380–385 nm; excitation in this range gives rise to two emission bands at 480 and 650 nm in solution. In the solid state, the complexes show photoluminescence only in the red range (λmax = 600–610 nm) with microsecond lifetimes.
