摘要：

(Figure Presented) A manifold of hydrogen-bonding options on a highly active, functionalized capsule surface exhibiting 20 crown ether type pores allows the fixation and recognition of 20 ammonium cations (see picture; W green, Fe orange, O red, N blue, H light gray), which are partially released in solution, thereby leading to related equilibria. © 2010 Wiley-VCH Verlag GmbH & Co.
