Ammonium–crown ether supramolecular cation-templated assembly of an unprecedented heterobicluster–metal coordination polymer with enhanced NLO properties

Abstract

An ammonium–crown ether host–guest supramolecular cation-templated synthetic methodology has been developed to construct a structurally unprecedented heterobicluster–metal coordination polymer (HCM-CP 1) based on tetranuclear clusters [WS₄Cu₃]⁺ with different connection environments, pentanuclear clusters [WS₄Cu₄]²⁺, and Cu⁺ building metal ions. HCM-CP 1 exhibits enhanced NLO properties, which may be ascribed to the incorporation of diverse building cluster components.
