We report the solvato-controlled synthesis of novel Pd2nLn-based bowl-shaped cages, specifically tetrafacial (n = 4) and trifacial 3), constructed using cis-blocked 90° Pd(II) acceptors a planar tetratopic ligand. The reaction ligand with (tmeda)Pd(ONO2)2 in water produced cage (C1), which quickly converted into (C2) dimethyl sulfoxide (DMSO). Alternatively, self-assembly (en)Pd(ONO2)2 yielded an equilibrium mixture (C3) (C4) cages that exhibited reversible structural transformations response to solvent changes. Notably, C3/C4 effectively encapsulated stabilized protonated merocyanine (MCH+), preventing its hydrolysis aqueous media enabling photoisomerization over multiple cycles. Additionally, both C1 displayed selective binding extraction benzene cyclohexane water, achieving 99% purity separation process excellent recyclability. This study presents first instance water-soluble molecular host capable selectively separating from through simple at ambient conditions, highlighting potential these for guest encapsulation, stabilization, chemical separations.
