Secondary sphere interactions from proximal phenyl side chains control the anion selectivity of dimeric Ln(III)[15-MCCu(II),α-aminoHA-5]3+ metallocavitands. CH–O interactions, which are only possible with certain side chains, are sufficient for overcoming an intrinsic energy barrier to binding saturated dicarboxylates in hydrophobic compartments.
