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.

一种柱[5]芳烃基超分子聚合物网络凝胶及其在吸附去除水中有机染料中的应用

通过易于合成的三足客体（SZ）和硫代乙酰腙功能化的双柱[5]芳烃主体（DP5）成功构建了一种新型3D超分子聚合物网络凝胶（DP5G）。有趣的是，DP5G 显示出聚集诱导发射（AIE）。此外，DP5G 显示出 3D 网络结构，可用于染料去除实验。值得注意的是，干凝胶 DP5G 可以有效去除水溶液中的阳离子染料（包括结晶紫和罗丹明 B），去除率分别为 96.3% 和 95.4%。此外，DP5G对结晶紫和罗丹明B的最大吸附容量分别为19.65 mg/g和22.85 mg/g。进一步研究了 3D 超分子聚合物网络凝胶 (DP5G) 的稳定性，其对外部刺激如 pH、
