摘　　要：Hydrazine hydrate(DH)is a widely used chemical agent,but it is highly toxic.Thus,the development of low-cost and easy-to-prepare materials for the detection and adsorption of DH is very significant.Herein,a novel and easy-to-prepare supramolecular smart material based on bisquinoline-functionalized naphthalene diimide(DQ8)has been designed and synthesized.In the DQ8,the synergistic effect between quinoline and naphthalene diimide groups has been employed to improve the selectivity and sensitivity for binding of DH.The DQ8-based crystalline porous material(DQ8-CPM)can simultaneously detect and adsorb DH and produce noticeable fluorescence color changes after adsorption of DH vapor.More significantly,the DQ8-CPM shows nice recycling performance on DH detection and adsorption.Meanwhile,a smart gel based on DQ8(DQ8-G)shows multi-channel response for DH through color,fluorescence,and state changes.The DQ8 shows high selectivity and sensitivity for DH.The detection limit of DQ8 for DH is 8.6×10^(-7) mol/L.According to the investigation of the DH binding and response mechanism,the synergistic effect between quinoline and naphthalene diimide groups plays an important role in the DH response process.It's a simple and feasible way to develop materials for detection and adsorption of DH through synergistic effects.
