摘要：

A novel 3D supramolecular polymer network gel (DP5G) was successfully constructed by easy to synthesize tripodal guest (SZ) and thioacetylhydrazone functionalized di-pillar[5]arene host (DP5). Interestingly, the DP5G showed aggregation induced emission (AIE). Moreover, the DP5G displayed a 3D network structure, which was used to dye removal experiments. Notably, the xerogel DP5G could effectively remove cationic dyes (including crystal violet and rhodamine B) from aqueous solution and the removal percentages are 96.3% and 95.4%, respectively. In addition, the maximal adsorption capacity of DP5G towards crystal violet and rhodamine B are 19.65 mg/g and 22.85 mg/g, respectively. The stability of the 3D supramolecular polymer network gel (DP5G) was further investigated, which exhibited excellent stability toward outer stimuli such as pH, competitive agents, oxidant and reducing agent.
