The present study demonstrates the development of a supramolecular porous ensemble consisting of hetero-oligophenylene derivative 6 and Au-Fe O nanodots. Supramolecular assemblies of AIE-active hetero-oligophenylene derivative 6 served as reactors for the generation of Au-Fe O nanodots. The as prepared supramolecular ensemble functioned as an efficient recyclable photocatalytic system for C(sp )-H bond activation of anilines for the construction of quinoline carboxylates. Interestingly, the "dip catalyst" prepared by depositing PTh-co-PANI-6: Au-Fe O nanodots on a filter paper served as a recyclable strip (up to 10 cycles) for C-C/C-N bond formation reaction.
本研究展示了由杂寡聚苯衍生物 6 和 Au-Fe O 纳米点组成的超分子多孔配合物的发展。具有 AIE 活性的杂寡聚苯衍生物 6 的超分子组装体作为生成 Au-Fe O 纳米点的反应器。所制备的超分子配合物作为一种有效的可回收光催化体系，用于 C(sp )-H 键活化苯胺，构建喹啉羧酸酯。有趣的是，通过将 PTh-co-PANI-6：Au-Fe O 纳米点沉积在滤纸上制备的“浸出催化剂”可作为用于 C-C/C-N 键形成反应的可回收条（多达 10 个循环）。
