| 英文摘要 | Despite the rise of uranyl-organic rotaxane compounds along with the prosperity of uranyl-organic frameworks, uranyl-based polyrotaxane compounds with high nuclearity have been rarely reported. In this work, a novel twofold nested uranyl polyrotaxane compound (1, [ (UO2)(3)O(OH)(3) (C4CA4@CB6)(1.5)]center dot[(UO2)center dot(OH) (H2O) (C4CA4@CB6)(0.5))]) with two different moieties, hexameric networks and dimeric chains, has been synthesized from C4CN4@CB6 (L1) using C4N4@CB6 (L3) as the induction agent. It is worth noting that the hexameric uranyl SBUs found here represent the highest nuclearity of uranyl found by far in uranyl-organic rotaxane frameworks. When starting from C4CN3@CB6, a positional isomer of C4CN4@CB6 (L2), compound 2 ([(UO2) (H2O) (NO3) (C4CA3@CB6)]center dot[(C4CA3@CB6)]) was obtained, which contains a one-dimensional polyrotaxane chain linked by another set of noncoordinated C4CA3@CB6 motifs through hydrogen bonding. Further characterization of compound 1 by fluorescence, IR, and Raman spectra was performed to analyze the features of the hexameric uranyl unit as well as dimeric unit. Meanwhile, the mechanism for the formation of 1 and 2 has been proposed by a comprehensive comparison with previously reported trimeric uranyl polyrotaxane networks, suggesting the vital role of self-template in the formation of uranyl-organic rotaxane frameworks, especially for hexameric uranyl unit in 1. |
