Abstract
Solvent-induced construction of two zinc supramolecular isomerism, sensing properties and adsorption of dye molecules.
Highlights
Supramolecular isomerism, which possesses the same molecular components but different network superstructures, represents an intriguing and important phenomenon in the construction of coordination compounds and has received considerable attention in recent decades.[1]
Many coordination polymers with supramolecular isomerism have been reported; controllable synthesis of supramolecular isomers still remains a long-term challenge because the self-assembly processes are o en in uenced by compositional and process parameters such as reaction temperature,[2] solvent,[3] template,[4] light,[5] reaction time,[6] concentration effect,[7] and pH value.2f,8 In a word, research on selfassembly, crystallization, and structure–property relationships for supramolecular isomerism is meaningful for crystal engineering of coordination compounds
Supramolecular isomerism has been categorized by Moulton and Zaworotko into four different kinds: structural, conformational, catenane, and optical isomerism.1a Hitherto, the commonly
Summary
Supramolecular isomerism, which possesses the same molecular components but different network superstructures, represents an intriguing and important phenomenon in the construction of coordination compounds and has received considerable attention in recent decades.[1]. The Zn center with slightly distorted octahedral geometry is coordinated with ve oxygen and one nitrogen from four independent cppca2À anions and one water molecule, differently from the trigonal bipyramidal geometry in compound 1 (Fig. 2a).
