One-electron reduction of 2,7-Bu-pyrene-4,5,9,10-tetraone (1) with potassium afforded two monoradicals 1K(cryp) and 1K(18c6), a radical tetramer [1K(15c5)]4 and a radical polymer (1K)2n. Using 1K(cryp) and 1K(18c6), we demonstrated large spin density modulation of an organic radical anion in the solid state by electrostatic attraction, without alternation of the molecular skeletons.
一电子还原 2,7-丁基芘-4,5,9,10-四酮（1）与钾得到两个单自由基 1K(cryp)和 1K(18c6)、一个自由基四聚体[1K(15c5)]4 和一个自由基聚合物(1K)2n。利用 1K(cryp)和 1K(18c6)，我们证明了在固态中通过静电吸引可以实现有机自由基阴离子的大自旋密度调制，而不改变分子骨架。
