Regio-defined syntheses of tetra-brominated dibenzo[g,p]chrysene scaffolds with high solubility

Regio-defined syntheses of tetra-brominated dibenzo[g,p]chrysene (DBC) derivatives are described, with a description of different patterns of the four-bromine-positions. These derivatives were designed with two features: one is installation of butyl groups for being processable in solution-phase, and the other is attachment of bromine atoms for being variable. Thus, these brominated devices would enable us to achieve diversity-oriented preparation of solution-processable DBC derivatives.
