Usage

Classification

Benzodithiophene, BDT, Thienopyrrole, Heterocyclic five-membered ring, Organic semiconducting materials, Low band gap polymers, Organic photovoltaics, Polymer solar cells, OFETs.

Applications

PBDTTPD, Poly[(5,6-dihydro-5-octyl-4,6-dioxo-4H-thieno[3,4-c]pyrrole-1,3-diyl)[4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b′]dithiophene-2,6-diyl], is one of the polymer semiconductors that gives high device performance in OPV solar cells. The thieno[3,4-c]pyrrole-4,6-dione (TPD) unit offers a planar structure which is beneficial for electron delocalization to promote intrachain and interchain interactions. It also has a strong electron-withdrawing effect, leading to relatively low HOMO and LUMO energy levels for the resulting polymer semiconductors. It has been demonstrated that linear n-octyl (rather than the branched ethyl-hexyl side chain on the acceptor moiety) enables a stronger electronic coupling with fullerene when PBDTTPD is built into OPV devices.

Description

PBDTTPD, Poly[(5,6-dihydro-5-octyl-4,6-dioxo-4H-thieno[3,4-c]pyrrole-1,3-diyl)[4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b′]dithiophene-2,6-diyl], is one of the polymer semiconductors that gives high device performance in OPV solar cells.

Uses

General Description

PBDT(EH)-TPD(Oct) is a conducting polymer with benzothiophene as the electron donor and thieno[3,4-c]pyrrole-4,6-dione as the electron withdrawing units. It can be used to form a π-conjugating system for the development of a variety of high performance electrochemical devices.
