Pillar[5]quinone (PQ[5])‐based porous polymer has been prepared by crosslinking and oxidating pillar[5]arene (PA[5]). Quinone was used as an unorthodox ligand to load palladium‐catalyst with high loading ratio (up to 12.0 wt %). Catalyst was well dispersed on solid support in the form of Pd2+‐specie. Pd‐loaded PQ[5]‐based heterogeneous catalyst was highly efficient for Suzuki‐coupling reactions (22‐ to 1485‐fold higher than Pd/C based on turnover frequency). It was superior compared to other existing heterogeneous catalysts for selective catalytic reaction. This heterogeneous catalyst had good thermo‐stability, and could be reused and recycled.

We report "pro-guest" and acyclic cucurbit[n]uril conjugated polymers as supramolecular drug delivery systems (DDSs). These supramolecular DDSs could encapsulate anti-tumor drugs. Under acidic conditions, an acid-labile "pro-guest" degraded to become a "competing guest", which displaced and released the encapsulated drug at a tunable rate.

of main observation and conclusion arene was used to construct supramolecular vesicles via host-guest interaction. Water-soluble 2,6-helic[6]arene was discovered to be high affinity host for suitable biomarkers. Supramolecular vesicles were responsive to multiple stimuli types, including temperature, pH, Ca 2+ , CO 2 bubbling and biomarker displacement. Supramolecular vesicles were used to load and deliver antitumor drug doxorubicin to HeLa cells in vitro.www.cjc.wiley-vch.de

The 14-pods Cu 7 S 4 hollow microcages wholly exposed with nanotwinned building blocks were successfully prepared by an ethanol-assisted sacrificial Cu 2 O template approach. Its photocatalytic activity for the degradation of methylene blue (MB) was determined. The results suggest that the Cu 7 S 4 microcages with nanotwinned building blocks possess higher catalytic activity than the Cu 7 S 4 microcages without the nanotwinned structures, suggesting that the special nanotwinned components can improve the catalytic performance of the multipod framework. Further investigate reveals that the nanotwins inside the Cu 7 S 4 microcages can facilite the transport of free charges, decrease the recombination of photoinduced electrons and holes, and elongate the lifetime of the electron-hole pairs. Our work will provide powerful evidence that the nanotwinned building blocks of the synthesized Cu 7 S 4 microcages play a crucial role for the high catalytic activity.
