英文摘要	A bi-1,3,4-oxadiazole derivative (BOXDH-T12) showed intramolecular charge transition at concentrations lower than 1 10-5 mol/L. The self-assembling behaviors of BOXDH-T12 depended on solvents that it self-assembled into H-aggregates in alcohols and slipped packing aggregates in DMSO. FTIR, 1H NMR and TGA results revealed that strong gelator-gelator hydrogen bonding interaction induced H-aggregation of BOXDH-T12 in alcohols and the interactions between DMSO and BOXDH-T12 molecules caused a slipped stacking. BOXDH-T12 can gel the mixtures of DMSO and ethanol through a cooperative effect of the hydrogen bonding, van der Waals interaction and - stacking forces, furthermore, helical ribbons could be observed in DMSO/ethanol due to DMSO molecule interacting. In alcohols, solvophobic/ solvophilic effect plays a critical role in gelation behaviors. 2013 Elsevier B.V. All rights reserved.
