The present teachings provide methods for providing populations of single-walled carbon nanotubes that are substantially monodisperse in terms of diameter, electronic type, and/or chirality. Also provided are single-walled carbon nanotube populations provided thereby and articles of manufacture including such populations.

Separation of carbon nanotubes in density gradients

A photoactive device includes a photoactive region disposed between and electrically connected to two electrodes where the photoactive region includes a first organic photoactive layer comprising a first donor material and a second organic photoactive layer comprising a first acceptor material. The first donor material contains photoactive polymer-wrapped carbon nanotubes and the photoactive region includes one or more additional organic photoactive material layers disposed between the first donor material layer and the acceptor material layer. The photoactive region creates excitons upon absorption of light in the range of about 400 nm to 1450 nm.
