Self-organization of dipyridylcalix[4]pyrrole into a supramolecular cage for dicarboxylates†
Abstract
Cis- and trans-dipyridylcalix[4]pyrroles were synthesized and cis-dipyridylcalix[4]pyrrole formed a supramolecular cage upon dimerization and coordination with Pd(II). The cage molecule recognised suberate selectively by hydrogen bonding to the two calix[4]pyrroles.
