A new class of organic photovoltaic materials: poly(rod-coil) polymers having alternative conjugated and non-conjugated segments

摘要

A new class of organic photovoltaic materials, poly(rod-coil) polymers composed of alternatively definite conjugated and non-conjugated segments, have been proposed. The first five examples based on poly-urethane chemistry showed photovoltaic performance surpassing the reference compound, but less dependent on their molecular weight.
