Icosidodecahedral Coordination-Saturated Cuprofullerene

The first coordination-saturated buckyball with a C60 molecule totally encased in an icosidodecahedral Cu30 in a (μ30 -(η2 )30 )-fashion, namely C60 @Cu30 @Cl36 N12 , has been successfully realized by a C60 -templated assembly. The 48 outmost coordinating atoms (36Cl+12N) comprise a new simple polyhedron that is described by a ccf topology. Charge transfer from (CuI , Cl) to C60 explains the expansion of the light absorption up to 700 nm, and accounts for an ultrafast photophysical process that underpins its high photothermal conversion efficiency. This work makes a giant step forward in exohedral metallofullerene (ExMF) chemistry.

A 1D Mixed-Valence Cuprofullerene Pyrazolate Polymer as a Semiconductor Material

Polymeric {Cu₆[(μ₃-η²:η²:η²)₂-C₆₀](FPz)₆Cl·3C₆H₅Cl}_∞ [FPz = 4-(trifluoromethyl)pyrazolate], synthesized solvothermally with chlorobenzene as the solvent, is a doubly-connecting trans bis-adduct hexanuclear cuprofullerene that has copper in mixed valence. The compound is an example of a metallofullerene having semiconductivity character.

Regioisomeric core-shell cuprofullerene C60@Cu24

The controlled synthesis of high-nuclear regioisomeric core-shell exohedral metallofullerenes (ExMFs) is challenging. Herein, we demonstrated the synthesis of regioisomeric core-shell cuprofullerene C₆₀@Cu^I₂₄ and its 3-D coordination polymer using heteroleptic ligands, realizing high-nuclear regioisomeric ExMFs and a polymeric ExMF structure.

Metal oxide adsorption on fullerene C60 and its potential for adsorption of pollutant gases; density functional theory studies

Combinations of fullerene and metal oxides (MOx) are interesting, not only because they display the individual properties of fullerene and of MOx nanoparticles, but they may also exhibit synergetic properties that are advantageous for gas sensing applications. In the present work, the adsorption of some different MOxs on fullerene C₆₀, and also the NO₂ and CO sensing properties of these complexes, have been theoretically studied. All quantum mechanical computations have been carried out using Gaussian G09, employing the DFT method at the B97D/6-311G(d,p) level. NBO theory has been used for analysis of the charge transfers during gas adsorption. The chemical nature of the newly formed bonds in the studied complexes and their relative strength have been analysed using AIM2000 software. The results show that MOx/C₆₀ complexes are much stronger adsorbents for NO₂ and CO than C₆₀ is. It is also expected that these complexes have more optical and electrical sensitivity in the selectivity towards gases, including NO₂ and CO.

Coordination assembly and host–guest chemistry of a triply interlocked [2]catenane

Triply catenated systems composed of two or more discrete coordination-metal cages through mechanical bonds exhibit excellent host–guest behaviors, which can be potentially applied in drug delivery systems.
