Abstract
We have synthesised and characterised a new low-gap conjugated polymer, with a broad absorption profile. In blends with a C-70 derivative we demonstrate power conversion efficiencies of 0.76%. We show electroluminescence from the polymer peaking at 956 nm, and quantum efficiency of 0.02% in a blend.
