Superior Anion-Binding Properties of a Cryptand-like Oligopyrrolic Macrocycle

Recognition by strapped system: Cryptand‐type calix[4]pyrrole are shown to exhibit a highly enhanced affinity towards anionic guests as compared to other reported calix[4]pyrroles (see figure). The results obtained provide some insights as to how calix[4]pyrrole‐based anion receptors may be designed...

Description
Summary:Recognition by strapped system: Cryptand‐type calix[4]pyrrole are shown to exhibit a highly enhanced affinity towards anionic guests as compared to other reported calix[4]pyrroles (see figure). The results obtained provide some insights as to how calix[4]pyrrole‐based anion receptors may be designed to achieve higher affinity and selectivity.
