HDOQx-DBrDF, high purity (>99%) monomer

Used in low band gap semiconducting polymers for organic photovoltaic devices


Specifications | MSDS | Literature and Reviews


HDOQx-DBrDF, namely 5,8-Dibromo-6,7-difluoro-2-((2-hexyldecyl)oxy)quinoxaline (CAS number 2269476-12-0), is a fluorinated quinoxaline derivative. Quinoxaline derivatives are widely used as electron deficient units in low bandgap semiconducting polymers for organic photovoltaic devices. Further introduction of fluorine atoms on the benzene ring makes electron density in the structure even poorer, downshifting the highest occupied molecular orbital (HOMO) energy level and increasing charge mobility of the targeted polymer donors. Fluorination also achieves fast charge separation and low nonradiative recombination loss in the PSCs, resulting both high VOC and JSC. Large hexyldecyloxy (HD) group is there to enhance absorption of the polymers and to improve the targeted polymers' solubility in most of the common solvents.

HDOQx-DBrDF has been used for the synthesis of PTQ10 as a highly efficient polymer semiconductor for NF-PSCs.
