摘要: A remarkable selectivity on the basis of size is observed for encapsulation Et4N+ in presence Me4N+ and Pr4N+ by a predesigned [Ga4L6]12− homochiral tetrahedral cluster (L=bis-bidentate ligand). Immediate quantitative stepwise replacement R4N+ counterions cavity 1H NMR spectroscopy (see below). The also solid state.
