The core–shell structure of endohedral fullerenes results in good protection of the encapsulated spin carriers from the environment. In this research, the quantum coherence behavior of the endohedral fullerene Sc3C2@C80 in CS2 solution is characterized from 5 K to room temperature. Below the critical temperature of around 140 K, the inner group is hindered, and the EPR spectrum consists of a single broad line. The spin carriers display a maximum phase memory time of 17.2(7) μs at 10 K. In the high temperature region, the inner group is mobile, and the EPR spectrum consists of 22 homogeneously broadened lines due to isotropic hyperfine coupling. The maximum phase memory time for each transition is around 139(1) ns at 200 K which allows arbitrary superposition state manipulations to be performed. This research demonstrates that Sc3C2@C80 displays temperature-crossover behaviour due to weak interaction between the Sc3C2 core and the C80 shell.

在量子位交叉的富勒烯富勒烯钪3 c ^ 2 @C 80 †
内表面富勒烯的核-壳结构可很好地保护封装的自旋载体免受环境的侵害。在这项研究中,内表面富勒烯Sc 3 C 2 @C 80在CS 2中的量子相干行为溶液的特征是从5 K到室温。在大约140 K的临界温度以下,内部基团受阻,EPR谱由一条宽线组成。自旋载流子在10 K时的最大相位存储时间为17.2(7)μs。在高温区域,内部基团是可移动的,由于各向同性的超精细耦合,EPR谱由22条均匀加宽的线组成。每个跃迁的最大相位存储时间在200 K时约为139(1)ns,这允许执行任意叠加状态操作。这项研究表明,由于Sc 3 C 2之间的弱相互作用,Sc 3 C 2 @C 80显示出温度交叉行为。核心和C 80外壳。
