Abstract An optimized synthetic protocol toward highly reactive Rieke zinc is applied for the preparation of a series of ω-(2, 5-dibromothiophene-3-yl) alkyl acetate monomers and statistical copolythiophenes derived thereof, with 10% of ester-functionalized side chains. The obtained conjugated polymers are attractive electron donor materials for organic solar cells, notably to increase the thermodynamic stability of the bulk heterojunction polymer: ...
