1Semiconducting Polymers Consisting of Anthracene and Benzotriazole Units for Organic Solar Cells.

Shin SA, Kim JH, Park JB, Hwang DH.

J Nanosci Nanotechnol. 2015 Feb;15(2):1515-9.

An alternating copolymer composed of 2,6-dibromo-9,10-bis(2-ethylhexyloxy)anthracene and benzotriazole units, poly(An-alt-BTz), was synthesized, through a Suzuki cross-coupling polymerization, for use in photovoltaic devices as a p-type electron donor. For the reduction of the bandgap energy of benzotriazole units, 5,5'-dibromo-2,2'-bithiophene, or 2,5-dibromothieno [3,2-b] thiophene units were introduced into the polymer. Read More
