Conformational tuning of magnetic interactions in coupled nanographenes

Phenalenyl (C₁₃H₉) is an open-shell spin-1/2 nanographene. Using scanning tunneling microscopy (STM) inelastic electron tunneling spectroscopy (IETS), covalently-bonded...菲那烯基自由基（Phenalenyl，分子式C₁₃H₉）是一种开壳层自旋1/2型纳米石墨烯。采用扫描隧道显微镜（scanning tunneling microscopy，STM）与非弹性电子隧穿谱（inelastic electron tunneling spectroscopy，IETS）对共价键合的……开展了研究。
