英文摘要	An interesting halogen-substituent effect on the organogelation properties of poly(benzyl ether) dendrons is reported. A new class of poly(benzyl ether) dendrons with halo substituents decorating their periphery was synthesized and fully characterized. A systematic study on the gelation abilities, thermotropic behaviors, aggregated microstructures, and mechanical properties of self-assembled organogels was performed to elucidate the halogen-substituent effects on their organogelation propensity. It was found that the exact halogen substitutions on the periphery of dendrons exert a profound effect on the organogelation propensity, and dendrons G(n)-Cl (n=2, 3) and G(2)-I proved to be highly efficient organogelators. The cooperation of multiple -, dispersive halogen, CH-, and weak C-HX hydrogen-bonding interactions were found to be the key contributor to forming the self-assembled gels. Dendritic organogels formed from G(n)-Cl (n=2, 3) in 1,2-dichloroethane exhibited thixotropic-responsive properties, and such thixotropic organogels are promising materials for future research and applications.
