Abstrakt: The present study demonstrates the development of a supramolecular porous ensemble consisting of hetero-oligophenylene derivative 6 and Au-Fe 3 O 4 nanodots. Supramolecular assemblies of AIE-active hetero-oligophenylene derivative 6 served as reactors for the generation of Au-Fe 3 O 4 nanodots. The as prepared supramolecular ensemble functioned as an efficient recyclable photocatalytic system for C(sp 2 )-H bond activation of anilines for the construction of quinoline carboxylates. Interestingly, the "dip catalyst" prepared by depositing PTh-co-PANI-6: Au-Fe 3 O 4 nanodots on a filter paper served as a recyclable strip (up to 10 cycles) for C-C/C-N bond formation reaction.
