Specifications | MSDS | Literature and Reviews


5,8-Dibromo-2,3-bis(3-(octyloxy)phenyl)quinoxaline (Quinoxaline-2PhO-2Br) is the building block for the synthesis of low band-gap polymer semiconductor materials (such as TQ1). Octyloxy as the side chain of quinoxaline functions to promote good solubility of the resulting polymer in organic solvents.
