摘要

The synthesis and gelation properties of a series of organogelators containing a benzohydrazide t nit and two alkoxy chains(oBn) were reported herein.oBn(n=8,10,12) could form stable gels in commercial fuels(e.g.,diesel),which were characterized by low critical gelation concentrations(CGCs) and good mechanical properties (G'＞105 Pa).The gelation process was further studied by field-emission scanning electron microscopy(FE-SEM),Fourier transform infrared spectroscopy(FTIR) and X-ray diffr action(XRD),etc.It was demonstrated that in these organogels,molecules self-assembled into fibrils 3D-network,where hydrogen bonding,van der Waals force and π-π interaction were confirmed as the driving forces.As compounds oBn(n=8,10,12) show very good gelation properties in diesel,their applications in oil spill treatment have also been tested.It was found that oBn could achieve rapid (＜30 s) and effective oil removal at room temperature,being good candidates for oil spill treatment in the future.Also,the removal efficiency could be as high as 95％.
