PTQ11, with better hole transport capability than PTQ10

Low cost, high purity polymer available online for fast, secure dispatch

Specifications | Pricing and Options | MSDS | Literature and Reviews

PTQ11 is a wide bandgap copolymer alternating electron withdrawing quinoxaline and electron donating thiophene units as the backbone. Comparing to the low cost polymer donor PTQ10, PTQ11 shows stronger molecular crystallization tendency and better hole transport capability.

Cyclic Voltammetry

cyclic voltammetry of polymer ptq11 in film
Cyclic voltammograms of the PTQ11 film on platinum electrode in 0.1M Bu4NClO4 in 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/Ag+ electrode as the reference electrode with a scanning rate of 100 mV/s in a 0.1 M tetrabutylammonium perchloroate Bu4NClO4) solution. The potential of Ag/Ag+ reference electrode was internally calibrated by using ferrocene/ferroncenium (Fc/Fc+) as the redox couple.
