D-A Copolymers Based on Thiophene Units

Scheme 2.9 Representative D-A copolymers based on thiophene units. Scheme 2.9 Representative D-A copolymers based on thiophene units.
The fluorene (FL) based D-A copolymers may be the first and most classical D-A copolymers based on bridged biphenyl derivatives (see Scheme 2.10). In 2003, Andersson et al reported the photovoltaic properties of a D-A copolymer containing a fluorine (FL) donor unit and BT with a thiophene n-bridge (DTBT) the PCE of the PSC based on PFDTBTrPCBM reached 2.2%. ... [Pg.63]

To further lower the band gap of cyan based PPVs below 2 eV, thiophene units with lower aromaticities have been incorporated into the main chain to form a D-A arrangement. Vanderzande et al. [132] developed copolymers based on the bis (l-cyano-2-thienylvinylene) phenylene prepared by Knoevenagel condensation to construct cyano vinylene linkages. Fig. 21. [Pg.364]
