A Highly‐Ordered 3D Covalent Fullerene Framework

Abstract

Ah ighly-ordered 3D covalent fullerene framework is presented with as tructure based on octahedrally functionalized fullerene building blocks in whiche very fullerene is separated from the next by six functional groups and whose mesoporosity is controlled by cooperative self-assembly with aliquid-crystalline blockcopolymer.The new fullerene-framework material was obtained in the form of supported films by spin coating the synthesis solution directly on glass or silicon substrates,followed by aheat treatment. The fullerene building blocks coassemble with aliquid-crystalline blockcopolymer to produce ah ighly ordered covalent fullerene framework with orthorhombic Fmmm symmetry,a ccessible 7.5 nm pores,a nd high surface area, as revealed by gas adsorption, NMR spectroscopy, small-angle X-rays cattering (SAXS), and TEM. We also note that the 3D covalent fullerene framework exhibits adielectric constant significantly lower than that of the nonporous precursor material.

Steering Metallofullerene Electron Spin in Porous Metal–Organic Framework

“…It can be seen clearly from Figure a–d that yttrium was well-distributed as carbon and zinc elements in Y 2 @C 79 N⊂MOF-177 crystal. EDS analysis (Figure e) and XPS measurement (Figure S5) for Y 2 @C 79 N⊂MOF-177 confirmed the existence of yttrium element originating from Y 2 @C 79 N. Furthermore, BET surface area shows a decrease from 894 m 2 g –1 in MOF-177 crystal to 721 m 2 g –1 in Y 2 @C 79 N⊂MOF-177 complex, indicating that the Y 2 @C 79 N molecules are encapsulated into the pore of MOF-177 rather than adsorbed on the crystal surface . Moreover, PXRD spectrum (Figure S6) of the Y 2 @C 79 N⊂MOF-177 is obviously different from that of pristine MOF-177.…”

Controlled deposition of fullerene derivatives within a graphene template by means of a modified Langmuir-Schaefer method

“…In addition, since fullerols have better solubility in water than brominated fullerene, nanotechnology can tune and control the fundamental physicochemical properties of fullerenes derivatives by ordering them into molecular thin films [38][39][40][41][42][43][44][45][46][47] fabricating either hydrophilic or hydrophobic nanocoatings. The possibility to control the size and the orientation of fullerene moieties in 2D arrangements can lead to new functional low-dimensional materials with interesting and promising properties for controllable wetting applications [26] including corrosion resistant [48], smart textiles [49], self-cleaning [50] and directional wetting [51] surfaces as well as for developing lab-on-a-chip (LOC) devices [52] and biosensors [26].…”

A hindered subphthalocyanine that forms crystals with included aromatic solvent but will not play ball with C60

“…STAM-1, [Cu3O21C30H24]n.5n(H2O), can be synthesized from the same starting materials as HKUST-1, Cu(NO3)2.3H2O and benzene-1,3,5-tricarboxylic acid (H3BTC), but by using a 50:50 water:methanol mix in place of ethanol as the solvent during the solvothermal synthesis. 78 During synthesis the H3BTC undergoes esterification, and upon crystallization, only monomethyl-esterified BTC ligands then link the same Cu paddlewheel nodes that are found in HKUST-1.…”
