Conjugated polymers can selectively wrap around single-walled carbon nanotubes (SWNTs) with specific chiral angles and diameters. Such a hybrid material containing both SWNTs and polymers is attractive for applications such as organic photovoltaic de

We report the synthesis of quaterrylene monomers and dimers from perylene inside single-walled carbon nanotubes (SWNTs). Excitation energy transfer (EET) from the encapsulated molecule to the SWNT is investigated by using femtosecond pump–probe spe

Doped conjugated polymers show high electrical conductivity due to doping-generated polarons, and understanding their transport properties is key to their practical use as transparent flexible electrodes. The transport properties have been widely stu
