摘要
Our childhoods may be recalled when a self-complementary cation, endowed with both a dibenzo[24]crown-8 macroring and a secondary dialkylammonium sidearm, self-assembles to form a two-component supramolecular architecture that is reminiscent of a daisy chain (depicted schematically on the right). This daisy-chain-like super-architecture is stabilized by a combination of [N+-H ··· O] hydrogen bonds and aryl-aryl stacking interactions.
