Abstract
Self-assembly gives rise to the versatile strategies of smart material design but requires precise control on the supramolecular level. Here, inorganic-organic synthons (conjugates) are produced by covalently grafting stearic acid tails to giant polyoxometalate (POM) Keplerate-type {Mo132} through an organosilicon linker (3-aminopropyltrimethoxysilane, APTMS). Using the liposome production approach, the synthons self-assemble to form hollow nanosized vesicles (100-200 nm in diameter), which can be loaded with organic dyes─eriochrome black T (ErChB) and fluorescein (FL)─where the POM layer serves as a membrane with subnanopores for cell-like communication. The dye structure plays an essential role in embedding dyes into the vesicle's shell, which opens the way to control the colloidal stability of the system. The produced vesicles are moved by an electric field and used for the creation of an infochemistry scheme with three types of logic gates (AND, OR, and IMP). To design 2D materials, synthons can form spread films, from simple addition on the water-air interface to lateral compression in the Langmuir bath, and highly ordered structures appear, demonstrating electron diffraction in Langmuir-Schaefer (LS) films. These results show the significant potential of POM-based synthons and nanosized vesicles to supramolecular design the diversity of smart materials.

Abstract
Two metallofullerene frameworks (MFFs) constructed from a penta-shell Keplerate cuprofullerene chloride, C60@Cu24@Cl44@Cu12@Cl12, have been successfully prepared via a C60-templated symmetry-driven strategy. The icosahedral cuprofullerene chloride is assembled on a C60 molecule through [η2-(C=C)]-Cu(I) and Cu(I)-Cl coordination bonds, resulting in the penta-shell Keplerate with the C60 core canopied by 24 Cu, 44 Cl, 12 Cu and 12 Cl atoms that fulfill the tic@rco@oae@ico@ico penta-shell polyhedral configuration. By sharing the outmost-shell Cl atoms, the cuprofullerene chlorides are connected into 2D or 3D (snf net) frameworks. TD-DFT calculations reveal that the charge transfer from the outmost Cu(I) and Cl to C60 core is responsible for their light absorption expansion to near-infrared region, implying anionic halogenation may be an effective strategy to tune the light absorption properties of metallofullerene materials.

Abstract
The self-assembly of porous molecular nanocapsules offer unique opportunities to investigate a range of interesting phenomena and applications. However, to design nanocapsules with pre-defined properties, thorough understanding of their structure-property relation is required. Here, we report the self-assembly of two elusive members of the Keplerate family, [Mo132 Se60 O312 (H2 O)72 (AcO)30 ]42- {Mo132 Se60 } 1 and [W72 Mo60 Se60 O312 (H2 O)72 (AcO)30 ]42- {W72 Mo60 Se60 } 2, that have been synthesised using pentagonal and dimeric ([Mo2 O2 Se2 ]2+ ) building blocks and their structures have been confirmed via single crystal X-ray diffractions. Our comparative study involving the uptake of organic ions and the related ligand exchange of various ligand sizes by the {Mo132 Se60 } and previously reported Keplerates {Mo132 O60 }, {Mo132 S60 } based on the ligand exchange rates, revealed the emergence of increased "breathability" that dominates over the pore size as we transition from the {Mo132 S60 } to the "softer" {Mo132 Se60 } molecular nano-container.

Abstract
In this work, the catalytic activity of core-shell-type polyoxometalate (POM) composites, comprised from Keggin POMs encapsulated in Mo72Fe30 Keplerate, in the oxidation of various sulfides into corresponding sulfoxides or sulfones and oxidative desulfurization of dibenzothiophene with hydrogen peroxide are investigated. From the results, the catalytic activity of these Keggins encapsulated in Keplerate are better than parent ones and among them BW12 ⊂ Mo72Fe30 showed the best results. The operationally simple oxidation reactions at room temperature, high to excellent yields and chemoselectivity, short reaction times, and the use of H2O2 as oxidant are some of the other advantages in this catalytic system. Also, the synergistic effect of Keggin POMs and Mo72Fe30 Keplarate has been confirmed.
