Abstract
A supramolecular material comprising a 2:2:2 assembly, the 2:2:2 assembly comprising a pair of macrocycles, two anionic species dimerized within the pair of macrocycles, each anionic species is a conjugate base of an organophosphoric acid moiety or a conjugate base of an organophosphonic acid moiety, and two cationic species, wherein each of the cationic species comprise a protonated nitrogen and each of the cationic species are hydrogen bonded by a N+—H···O salt bridge to an oxygen of the anionic species. Supramolecular polymers comprising a plurality of 2:2:2 assemblies are also provided. Methods for preparing the supramolecular materials are also provided.
Claims21
A supramolecular material comprising a 2:2:2 assembly, the 2:2:2 assembly comprising
- a pair of macrocycles,
- two anionic species dimerized within the pair of macrocycles, each anionic species is a conjugate base of an organophosphoric acid moiety or a conjugate base of an organophosphonic acid moiety,
- and two cationic species, wherein each of the cationic species comprise a protonated nitrogen and each of the cationic species are hydrogen bonded by a N+—H···O salt bridge to an oxygen of the anionic species.
A method for preparing a material, the method comprising:
- mixing macrocycles, first compounds having at least one tertiary amine moiety or at least one nitrogen-containing heteroaryl moiety, and second compounds having at least one phosphoric acid moiety or at least one phosphonic acid moiety,
- wherein the mixing is performed under conditions suitable for proton transfer from second compounds to first compounds and formation of N+—H···O salt bridges between first compounds and second compounds.
