  text: Highly selective rare-earth separation has become increasingly important due
    to the indispensable role of these elements in various cutting-edge technologies
    including clean energy. However, the similar physicochemical properties of rare-earth
    elements (REEs) render their separation very challenging, and the development
    of new selective receptors for these elements is potentially of very considerable
    economic and environmental importance. Herein, we report the development of a
    series of 4-phosphoryl pyrazolone receptors for the selective separation of trivalent
    lanthanum, europium, and ytterbium as the representatives of light, middle, and
    heavy REEs, respectively. X-ray crystallography studies were employed to obtain
    solid-state structures across 11 of the resulting complexes, allowing comparative
    structure–function relationships to be probed, including the effect of lanthanide
    contraction that occurs along the series from lanthanum to europium to ytterbium
    and which potentially provides a basis for REE ion separation. In addition, the
    influence of ligand structure and lipophilicity on lanthanide binding and selectivity
    was systematically investigated via n-octanol/water distribution and liquid–liquid
    extraction (LLE) studies. Corresponding stoichiometry relationships between solid
    and solution states were well established using slope analyses. The results provide
    new insights into some fundamental lanthanide coordination chemistry from a separation
    perspective and establish 4-phosphoryl pyrazolone derivatives as potential practical
    extraction reagents for the selective separation of REEs in the future.
