Peripherally Dimethyl Isophthalate-Functionalized Poly(benzyl ether) Dendrons: A New Kind of Unprecedented Highly Efficient Organogelators

摘要

Recently, dendritic gelators have gained much interest due to the advantages of well-defined and tunable structures and the capability of forming multiple noncovalent interactions. So far, a number of physically thermoreversible hydrogel and organogel systems consisting of dendrons or dendrimers with different chemical functionalities have been reported. Among the successful examples reported, the incorporation of amide units into the core or the branches of the dendritic organogelators has been considered very necessary for the effective gelation process. In contrast, the design of organogelators, particularly dendritic ones bearing no hydrogen-bonding motifs and/or long alkyl side chains, has been a great challenge. Herein, we report a new kind of unprecedented highly efficient dendritic organogelators, which contain no conventional gelating motifs but form gels in various aromatic and polar organic solvents, and even in aqueous media.
