We investigate the polarizability of trimetallic nitride endohedral fullerenes by partitioning the total polarizability into site specific components. This analysis indicates that the polarizability of the endohedral fullerene is essentially due to the outer fullerene cage and has insignificant contribution from the encapsulated unit. Thus, the outer fullerene cages effectively shield the encap...

In this paper, we introduce two combinatorial operations and a knot-theoretical approach for generation and description of fullerene architectures. The ‘Spherical rotating–vertex bifurcation’ operation applied to original fullerene polyhedra can lead to leapfrog fullerenes. However, the ‘Spherical stretching–vertex bifurcation’ operation applied to fullerene generates a family of related polyhe...

A series of donor-acceptor type co-crystals of fullerene (as the acceptor) and arylthio-substituted tetrathiafulvalene derivatives (Ar-S-TTF, as the donor) were prepared and their structural features were thoroughly investigated. The formation of co-crystals relies on the flexibility of Ar-S-TTF and the size matches between Ar-S-TTF and fullerene. Regarding their compositions, the studied co-cr...

In this paper, we examine the possibility of utilizing non-concentric nested fullerenes C60@CN , where N = 240, 540, 960 and 1500 as nano-oscillators for future nanoelectromechanical applications, such as vibration sensing and energy harvesting devices. We assume that the interactions between a fullerene C60 and a larger fullerene CN are dominated by the van der Waals forces which can be modele...

Abstract: The sphere-shaped fullerene has attracted considerable interest not least due to the peculiar electronic properties of this carbon allotrope and the fascinating materials emanating from fullerene-derived structures. The rapid development and tremendous advances in organic chemistry allow nowadays the modification of C60 to a great extent by pure chemical means. It is therefore not sur...

Despite numerous organic semiconducting materials synthesized for organic photovoltaics in the past decade, fullerenes are widely used as electron acceptors in highly efficient bulk-heterojunction solar cells. None of the non-fullerene bulk heterojunction solar cells have achieved efficiencies as high as fullerene-based solar cells. Design principles for fullerene-free acceptors remain unclear ...

A single isomer of fullerene bisadduct, PC61PF, was obtained from commercially available fullerene derivative, PC61BM, in one pot over two steps. The tether-directed remote functionalization approach provided a very simple and fast method to produce a single isomer of fullerene bisadduct with good yield and easy purification. Bulk heterojunction organic solar cells containing the bisadduct was ...
