The fusion and fission behaviors of exosomes are essential for the cell‐to‐cell communication. Developing exosome‐mimetic vesicles with such behaviors is of vital importance, but still remains a big challenge. Presented herein is an artificial supramolecular vesicle that exhibits redox‐modulated reversible fusion‐fission functions. These vesicles tend to fuse together and form large‐sized vesicles upon oxidation, undergo a fission process and then return to small‐sized vesicles through reduction. Noteworthy, the aggregation‐induced emission (AIE) characteristics of the supramolecular building blocks enable the molecular configuration during vesicular transformation to be monitored by fluorescence technology. Moreover, the presented vesicles are excellent nanocarrier candidates to transfer siRNA into cancer cells. [ABSTRACT FROM AUTHOR]

Hydration water greatly impacts the color of inorganic crystals, but it is still unknown whether hydration water can be utilized to systematically manipulate the emission color of organic luminescent groups. Now, metal ions with different hydration ability allow fine‐tuning the emission color of a fluorescent group displaying aggregation induced emission (AIE). Because the hydration water can be removed easily by gentle heating or mechanical grinding and re‐gained by solvent fuming, rewritable materials can be fabricated both in the hot‐writing and cold‐writing modes. This hydration‐facilitated strategy will open up a new vista in fine‐tuning the emission color of AIE molecules based on one synthesis and in the design of smart luminescent devices.

The co‐assembly of spherical colloids and surfactant–cyclodextrin microtubes yields a library of dynamic colloid‐in‐tube structures, including helices. In situ observations of these structures, including their thermo‐reversible assembly and disassembly, demonstrate the potential of the interplay between molecular and colloidal self‐assembly, thereby providing a novel route to temperature‐sensitive particle alignment and release.

Hierarchical self‐assembly is often exploited by nature to build complex functional entities. A similar approach yielded a library of dynamic colloid‐in‐tube structures, such as colloidal zigzags, double‐ and triple‐helices, by utilizing the thermo‐reversible co‐assembly of colloidal spheres and molecular microtubes, as reported by J. Huang, A. V. Petukhov, et al. in their Communication on page 3364 ff. The assembly and disassembly of these structures near human body temperature was explored in situ and in real time.
