| Abstract: | The amidourea-based homoduplex was developed as a super organogelator,which could form stable gels in wide-tested solvents.And the reversible gel to solution transition was responsive to heat/cool and acid/base stimuli.The organogels were extensively investigated by 1 H NMR,UV-visible absorption spectroscopy,fluorescence spectroscopy,scanning electron microscopy,transmission electron microscopy and powder X-ray diffraction.Based on these data,the gelation mechanism was rationally proposed.The hydrogen-bonded homoduplexes served as the basic assembling units,and further aggregated into three dimensional networks via-stacking and van der Waals interactions,which consequently led to the entangled fibers for the gel formation. |
