General description

Poly(3-octylthiophene-2,5-diyl-co-3-decyloxythiophene-2,5-diyl) (POT-co-DOT) is a regioregular conducting copolymer, which can be used as a donor material in electrochemical devices. It has a small band gap and forms an absorption spectrum in the red and infrared regions.
Typical Octyl thiophene:Decyloxythiophene = 1:1 (molar ratio). Synthesis, electrochemical and photophysical properties of poly(3-octylthiophene-2,5-diyl-co-3-decyloxythiophene-2,5-diyl)s (POT-co-DOT) copolymer via condensation polymerization has been reported. Application of POT-Co-DOT to electrophoretic deposition has been reported in a separate study.

Application

Conducting polymer
POT-co-DOT can be used as a conjugating polymer for the fabrication of polymeric solar cells (PSCs) and bulk heterojunction based solar cells with power conversion efficiency (PCE).

Electrophoretic deposition is a useful and efficient technique to deposit conjugated polymers, if suitable suspension of the target polymer is obtained. Unfortunately, neither general theory nor universal procedure for the preparation of a suspension suitable for electrophoretic deposition has seemed

Low band gap conjugated polymers with proper energy levels for charge transfer are required to achieve high-efficiency polymer solar cells. We report the synthesis and characterization of two new regioregular copolymers that are based on 3-alkoxythiophene monomers: poly(3-octylthiophene-2,5-diyl-co-3-decyloxythiophene-2,5-diyl) (POT-co-DOT) and
