Abstract
- The synergy among twelve carboxylates from two hexavalent baskets 1<superscript>6−</superscript> assisted the encapsulation of one divalent diammonium guest 3<superscript>2+</superscript>–6<superscript>2+</superscript> and the formation of ternary [3–6⊂1<subscript>2</subscript>]<superscript>10−</superscript>. The reduction of basket's multivalency, by photoinduced α-decarboxylation of 1<superscript>6−</superscript> to give 2<superscript>3−</superscript>, intercepted the interannular cooperativity operating in the stabilization of capsulpex [3–6⊂1<subscript>2</subscript>]<superscript>10−</superscript> to dramatically diminish the binding affinity towards diammonium guests. As a result, the cationic guests were released into bulk water with 2<superscript>3−</superscript> assembling into nanoparticles. With numerous drugs carrying positive sites, the finding reported here could now be examined for their light-promoted spatiotemporal delivery. [ABSTRACT FROM AUTHOR]
