carbazole based ligands with different lengths were assembled with nickel ions to construct metal–organic macrocycles. High-resolution mass spectrometry and ion mobility-mass spectrometry have been used to analyse the resulting MnLn assembly coexisting in solution. Combining with the structural analysis of their solid confirmation, it was revealed that the diversity of the metal–organic macrocycles was increased
将一系列不同长度的咔唑基配体与镍离子组装在一起,以构建金属有机大环化合物。高分辨率质谱和离子淌度质谱已用于分析溶液中共存的M n L n组装体。结合对其固体确认物的结构分析,发现金属有机大环的多样性随配体的柔性而增加。
