Acidic open-cage solution containing basic cage-confined nanospaces for multipurpose catalysis.

ABSTRACT: The nanoscale chemical spaces inherent in porous organic/coordination cages or solid/liquid materials have been continuously explored for their nanoconfinement effect on selective adsorption and reaction of small gas or organic molecules. Herein, we aim to rationalize the unconventional chemical reactivities motivated by the cage-confined nanospaces in aqueous solutions, where the robust yet permeable nanospaces defined by the open cages facilitate dynamic guest exchange and unusual chemical reactions. The high positive charges on [(Pd/Pt)₆(RuL₃)₈]²⁸⁺ nanocages drive imidazole-proton equilibrium to display a significantly perturbed pK _a shift, creating cage-defined nanospaces in solution with distinct intrinsic basicity and extr
