High Purity Polymer Donor for Organic Solar Cells
Improved solubility and polymer crystallinity with appropriate miscibility
Specifications | MSDS | Literature and Reviews | Technical Support
P5TCN-F25 is a derivative of polythiophenes (PTs) with cyano, fluoro and alkyl groups on the main backbone of the polymer. The branched 2-hexyldecyl alkyl chains are there to promote the solubility of the polymer and backbone fluorination is believed to lead to stronger interchain interaction, improved polymer crystallinity, and appropriate miscibility with fullerene or non-fullerene acceptors. Meanwhile, the cyano-group on the thiophene ring can not only down-shift the energy levels but also improve the crystallinity of the resulting polymers.
For large volume orders of 5-10 grams, please enquire. The lead time is 4-6 weeks.
