A Supramolecular Ferroelectric Realized by Collective Proton Transfer

摘要

Hydrogen bonds, which bind two or more electronegative atoms as X-H…Y, have been utilized to construct molecular assemblies in crystal engineering, supramolecular chemistry, and molecular recognition. The dynamics of proton transfer through hydrogen bonds has attracted extensive interest, because of the crucial role played by proton transfer in many chemical reactions and biological functions, and also because of its potentially diverse applications in electronic and optical devices.
