A conjugated polymer for near infrared optoelectronic applications
Artikel i vetenskaplig tidskrift, 2007
A conjugated polymer was prepd. based on 2-thia-1,3,5,8-tetraaza-cyclopenta[b]naphthalene central electron accepting unit and electron donating thiophene units on each side, LBPP-1, with unusually low band-gap (ca. 1.0 eV). Light absorption and photovoltaic response up to 1200 nm in composites with fullerene were demonstrated. The performance of solar cells contg. LBPP-1 is described and the suitability of LBPP-1 for photodetection in the IR region is discussed.
