摘要： A novel bis-coumarin gelator W was designed and synthesized. The W has good gel behavior in ethanol, tert-butanol, and isopropanol solutions. The self-assembly mechanism of the W was investigated using techniques such as UV–Vis absorption spectroscopy, infrared spectroscopy, and XRD. The results show that the driving forces for gelation are: π-π stacking, hydrogen bonding, and van der Waals forces, respectively. The effect of solvent on the gelation behavior is analyzed in the Teas plot, which shows that the solvent and the W can only form gels under the appropriate force. Through the optical performance test, the W can specifically recognize Al3+. The detection limit is as low as 7.32 × 10−7 M, the complexation constant is Ka = 1.033 × 103M−1. In addition, the cytotoxicity test of the two cell lines shows that their toxicity is low, which indicates that the W can be used in the field of bioengineering.
