A Dimetallic Cage with a Long Ellipsoidal Cavity for the Fluorescent Detection of Dicarboxylate Anions in Water

摘要

Host-guest chemistry is governed by the principle of size and shape complementarity:given a particular guest,a concave host must be designed whose cavity presents geometrical features complementary to those of the guest.Moreover,the cavity must offer groups capable of establishing strong yet reversible interactions with the guest.
