Electrospray ionization of THF solutions of preformed [K(18-c-6)][M(COT)2] (M = Dy(III), Y(III); COT = C8H82–,18-c-6 = C12H24O6) yields the isolated species [(M(COT)2)n+1 + nK]− with n = 0–3. High-resolution ion mobility spectrometry combined with density functional theory calculations performed for the n = 0–2 aggregates indicate that anionic multidecker stacks interlinked by potassium cations are formed. The alternating metal ions are aligned linearly: COT2––M3+–COT2––K+–COT2––M3+–COT2–. The different M3+ ionic radii lead to slight but resolvable changes in mobility and thus collision cross sections indicative of different overall heights of the multidecker stacks. CID measurements show that the aggregates fragment by cleavage at the K+ interconnections.

碱交联钇和镝双环辛四烯的阴离子堆分离
预制 [K(18-c-6)][M(COT) 2 ] (M = Dy(III), Y(III); COT = C 8 H 8 2– ,18-c-的 THF 溶液的电喷雾电离6 = C 12 H 24 O 6 ) 产生分离物种[(M(COT) 2 ) n +1 + n K] -其中n = 0-3。高分辨率离子迁移谱结合密度泛函理论计算对n = 0-2 聚集体进行表明,形成了由钾阳离子互连的阴离子多层堆叠。交替金属离子呈线性排列:COT 2– –M 3+–COT 2– –K + –COT 2– –M 3+ –COT 2–。不同的 M 3+离子半径导致迁移率的轻微但可解决的变化,因此碰撞横截面表明多层堆叠的不同总高度。CID 测量显示聚集体通过在 K +互连处的切割而破碎。
