Cubosomes are bicontinuous cubic-phase particles generated by amphiphile self-assembly with bicontinuous cubic phases, which creates an intricate network of interconnected nanochannels that endow these materials with special functions for advanced applications. On the other hand, clusters are an attractive class of molecules that exhibit intriguing functions and properties that differ from those of atoms and nanoparticles. Inspired by lipid self-assembly and attracted to the new functionalities of clusters, we prepared special heterocluster Janus dumbbells (HCJDs) composed of dissimilar nanoclusters: namely, a polyoxometalate and a polyhedral oligomeric silsesquioxane. HCJDs resemble conventional amphiphiles and, as such, they self-assemble in solution into faceted hybrid cubosomes via the transformation of vesicles into spongelike aggregates. Multiple mechanisms that lead to equilibrium, including molecular self-assembly, vesicle accumulation, membrane fusion, inner-structure reorganization, and cubic crystal growth, contributed to the overall process. On the basis of these results, we proposed a strategy for self-assembly - from basic molecular design that goes beyond traditional amphiphiles to the construction of micro- or nanomaterials with hierarchical structures and advanced functions.

Hydroarylation of internal alkynes by cost-effective CoIII-catalysis, directed by N-tert-butyl amides, is achieved to avail mono- or dihydroarylated amide products selectively in an atom and step economic way. Several important functional groups were tolerated under the reaction conditions, and syn-hydroarylation products were exclusively isolated. Notably, a 4-fold C-H hydroarylation provided a highly conjugated organic framework in one step. Kinetic study with extensive deuterium labeling experiments were performed to support the proposed mechanism.

Two new enlarged tetraarylethene-based compounds in which biphenyl and 4,5,9,10-tetrahydropyrene cores connect multiple arylethene units have been synthesized through convenient synthetic procedures. The optical properties and electrochemical properties of the two compounds have been investigated. The two compounds possess high emission efficiency in solid state. Particularly, the absolute fluorescence quantum yield of 4,5,9,10-tetrahydropyrene-cored compound in a solid film is up to 44.1%. The emissions of the two compounds in solutions are very weak but they become strong emitters in solid state or in poor solvents, showing aggregation-induced emission (AIE) characteristics. The two compounds exhibit high thermal stability with Td above 427 °C and show relatively high glass transition temperature with Tg above 142 °C.
