研究了溶液和气相卤化物与双锑（iii）阴离子受体的结合。这类新的阴离子受体利用了与极性的Sb-O键形成相反的以sb为中心的强二级键相互作用（SBIs）。1H NMR滴定数据统计拟合结合模型，提取溶液相结合能量，同时用ESI-MS观察阴离子-受体复合物的形成。密度泛函理论计算表明，它们对结合卤化物阴离子的亲和力被DMSO中强烈的显式溶剂化效应所减轻，这为未来设计绕过直接溶剂结合的设计提供了见解，并有望在阴离子结合方面产生更紧密和更强的选择性。
The solution and gas phase halide binding to a bis-antimony(iii) anion receptor was studied. This new class of anion receptors utilizes the strong Sb-centered secondary bonding interactions (SBIs) that are formed opposite to the polar Sb-O primary bond. 1H NMR titration data were fitted statistically to binding models and solution-phase binding energetics were extracted, while the formation of anion-to-receptor complexes was observed using ESI-MS. Density functional theory calculations suggest that their affinity towards binding halide anions is mitigated by the strong explicit solvation effect in DMSO, which gives insights into future designs that circumvent direct solvent binding and are anticipated to yield tighter and perhaps more selectivity in anion binding.
