Abstrakt: The present study demonstrates the development of a supramolecular porous ensemble consisting of hetero‐oligophenylene derivative 6 and Au‐Fe3O4 nanodots. Supramolecular assemblies of AIE‐active hetero‐oligophenylene derivative 6 served as reactors for the generation of Au‐Fe3O4 nanodots. The as prepared supramolecular ensemble functioned as an efficient recyclable photocatalytic system for C(sp2)−H bond activation of anilines for the construction of quinoline carboxylates. Interestingly, the "dip catalyst" prepared by depositing PTh‐co‐PANI‐6: Au‐Fe3O4 nanodots on a filter paper served as a recyclable strip (up to 10 cycles) for C−C/C−N bond formation reaction. Reaping the harvest: The as‐prepared AIE‐active supramolecular ensemble could harvest ambient visible light and can be utilized as efficient and recyclable "dip strip" photocatalyst for C(sp2)−H bond activation for the construction of quinoline carboxylates via C−H activation.
