AI Article Synopsis
- The study addresses the challenge of mimicking biomolecules to create homospiral structures using a blend of inorganic polyoxometalates (POMs) and organic cyclodextrin.
- Chiral double-helical chains were successfully formed through a specific arrangement of complexes, allowing for chiral transfer from molecules to the larger superstructure.
- This research enhances the understanding of POM-based materials and demonstrates their potential for selective interactions in chemical applications.
Article Abstract
The ability to conceptually mimic biomolecules to construct emergency-functional homospiral aggregates remains a long-standing challenge. Herein, we report artificial homohelical assembly by blending inorganic polyoxometalates (POMs) and organic cyclodextrin molecules. The chiral double-helical chains have been achieved by a left-hand arrangement of trimer-trimer. The trimer is formed by three {Mo}@α-CD inclusive complexes as a Whittaker-style paddle wheel. During the process of assembly, chiral transfer and amplification from molecule to superstructure were observed. The enantioselective adsorption of the homohelical aggregate toward (R/S)-1,1'-binaphthyl-2,2'-diamine was further demonstrated. The interaction of {Mo} and α-CD in solution was investigated. This work opens a wide scope for the design of a homohelix, enriching POM-based inorganic-organic materials.
