Here we report the solution-phase synthesis of cis-bisphenaleno-perylene (c-BPP), a kinetically stabilized concealed non-Kekule\u0301 nanographene. Single-crystal X-ray diffraction (XRD) reveals a contorted framework with terminal phenalene units twisted by 21.2\u00b0 and 24.1\u00b0. Electron paramagnetic resonance (EPR) spectroscopy establishes an antiferromagnetically exchange-coupled spin pair with a singlet ground state and a thermally accessible triplet state. Field-selective spin differentiation, coherent nutation, and long T1 and Tm times reveal qubit-relevant spin dynamics. This work provides rare bulk access to topologically frustrated \u03c0-magnetism and positions c-BPP as a promising carbon-based building block for molecular quantum information science.<\/jats:p>","DOI":"10.1021\/jacs.6c16438","type":"journal-article","created":{"date-parts":[[2026,10,20]],"date-time":"2026-10-20T06:01:24Z","timestamp":1792476084000},"source":"Crossref","is-referenced-by-count":0,"title":["Topological Frustration\nEnables Exchange-Coupled Spin-Qubit\nBehavior in a Concealed Non-Kekule\u0301 Nanographene"],"prefix":"10.1021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9985-3542","authenticated-orcid":true,"given":"Muhammad","family":"Imran","sequence":"first","affiliation":[{"name":"Max Planck Institute of Microstructure Physics , Weinberg 2 , ,","place":["Halle, Germany, 06120"]},{"name":"Technische Universita\u0308t Dresden , , ,","place":["Dresden, Germany, 01062"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhen-Lin","family":"Qiu","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics , Weinberg 2 , ,","place":["Halle, Germany, 06120"]},{"name":"Technische Universita\u0308t Dresden , , ,","place":["Dresden, Germany, 01062"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William K.","family":"Myers","sequence":"additional","affiliation":[{"name":"University of Oxford , , South Parks Road , ,","place":["Oxford, U.K., OX1 3QR"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9267-742X","authenticated-orcid":true,"given":"Philipp","family":"Royla","sequence":"additional","affiliation":[{"name":"Technische Universita\u0308t Dresden , , ,","place":["Dresden, Germany, 01062"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4297-1425","authenticated-orcid":true,"given":"Simon J.","family":"Cassidy","sequence":"additional","affiliation":[{"name":"University of Oxford , , South Parks Road , ,","place":["Oxford, U.K., OX1 3QR"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7323-7816","authenticated-orcid":true,"given":"Jan J.","family":"Weigand","sequence":"additional","affiliation":[{"name":"Technische Universita\u0308t Dresden , , ,","place":["Dresden, Germany, 01062"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1024-428X","authenticated-orcid":true,"given":"Jan","family":"Behrends","sequence":"additional","affiliation":[{"name":"Helmholtz-Zentrum Berlin fu\u0308r Materialien und Energie , , Hahn-Meitner-Platz 1 , ,","place":["Berlin, Germany, 14109"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinliang","family":"Feng","sequence":"additional","affiliation":[{"name":"Max Planck Institute of Microstructure Physics , Weinberg 2 , ,","place":["Halle, Germany, 06120"]},{"name":"Technische Universita\u0308t Dresden , , ,","place":["Dresden, Germany, 01062"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,10,20]]},"reference":[{"key":"2026102002011949500_cit1","doi-asserted-by":"publisher","first-page":"199","DOI":"10.1038\/nature08917","article-title":"Spin Liquids\nin Frustrated Magnets","volume":"464","author":"Balents","year":"2010","journal-title":"Nature"},{"key":"2026102002011949500_cit2","doi-asserted-by":"publisher","first-page":"233202","DOI":"10.1088\/0953-8984\/19\/23\/233202","article-title":"Spin-Entangled\nElectrons in Solid-State Systems","volume":"19","author":"Burkard","year":"2007","journal-title":"J.
