Borafullerenes are a class of

heterofullerene Heterofullerenes are classes of fullerenes, at least one carbon atom is replaced by another element. Based on spectroscopy, substitutions have been reported with boron ( borafullerenes), nitrogen (azafullerenes), oxygen (oxafullerenes), arsenic (ars ...
