A new conjugated polymer, LBPP-1, with an unusually low band-gap (ca. 1.0 eV) is presented. Light absorption and photovoltaic response up to 1200 nm in composites with a fullerene is demonstrated. Solar cell performance is presented and the polymer's suitability for photodetection in the infrared region is discussed.
