Cation-controlled capture of polyoxovanadate-based organic-inorganic 1D architectures

Chem Commun (Camb). 2022 Dec 1;58(96):13397-13400. doi: 10.1039/d2cc04379c.

Abstract

Metal cations are used to control the selective crystallization of organic-inorganic supramolecular polymers. Two complementary monomers, a dodecanuclear vanadate [V12O32(NO3)]5- and the organic macrocycle cyclen assemble into hybrid host-guest aggregates. In the presence of Ba2+ or La3+, supramolecular polymerization and crystallization is driven by a complex interplay of cyclene protonation, hydrogen-bonding and electrostatics.
