Structure and electronic properties of the nanopeapods-One dimensional C60O polymer encapsulated in single-walled carbon nanotubes

► Several novel peapods encapsulating one dimensional C60O polymers are constructed. ► Interwall distance of the two most stable peapods is in the Van der Waals scope. ► All peapods studied are stiffer than the corresponding SWCNTs. ► These peapods have high mobilies-in the order of 102-105 cm2 V−1 s−1.
