PTO2, high quality polymer donor

Simple structure with great device performance efficiencies


Specifications | Pricing and Options | MSDS | Literature and Reviews


PTO2 is an alternating wide band-gap copolymer with electron-donating benzodithiophene (BDT) and electron-withdrawing thiophene carboxylate ester as the main backbone units. PTO2 enjoys good solubility in non-halogenated solvents, i.e. xylenes and THF.

With an efficient charge generation at a low driving force, an efficiency of 14.7% was achieved in a single-junction OPV by using polymer donor PTO2 and a nonfullerene acceptor IT-4F.

PTO2 is considered as good replacement for PBDB-T-2F (PM6) or PTB7-Th for it similar but simpler structure, while maintaining great device performance efficiencies at lower costs.
