PBDB-TF-T1, high purity semiconducting polymer

High quality and available for fast, secure dispatch

PBDB-TF-T1 is a randomly copolymerised conjugated semiconducting polymer with benzodithiophene (BDT), Benzodithiophene dione (BDD) and thiophene carboxylate ester as the main backbone units. PBDB-TF-T1 is a close relative in structure to PBDBT-2F (PM6) and PTO2, relatively blue shifted in absorption to PM6 and red shifted to PTO2.

PBDB-TF-T1 is also relatively more soluble in non-halogenated solvents, i.e. o-xylene, 1,2,4‐trimethylbenzene or THF than PM6. Non-fullerene polymer solar cells withnon-halogenated solvent additive DIO from BTP-4F-12 as acceptor and PBDB-TF-T1 as polymer donor achieved high device performance efficiencies of PCE = 16.1%.

Please refer to our collection of green energy materials for non-halogenated solvents processing choice of non-fullerene acceptors (NFAs).

Cyclic Voltammetry

pbdb-tf-t1 cyclic voltammetry in film
Cyclic voltammograms of the PBDB-TF-T1 film on platinum electrode in 0.1M Bu4NClO4in acetonitrile at a scan rate of 100 mV s−1.

The cyclic voltammograms (CV) measurements were recorded on Ossila Potentiostat by using a three-electrode system with platinum disc as the working electrode, platinum wire as the counter electrode, Ag/Agelectrode as the reference electrode with a scanning rate of 100 mV/s in a 0.1 M tetrabutylammonium perchlorate (Bu4NClO4) solution. The potential of Ag/Ag+ reference electrode was internally calibrated by using ferrocene/ferroncenium (Fc/Fc+) as the redox couple.

To the best of our knowledge the information provided here is accurate. However, Ossila assume no liability for the accuracy of this page. The values provided are typical at the time of manufacture and may vary over time and from batch to batch. Products may have minor cosmetic differences (e.g. to the branding) compared to the photos on our website.
