Pyrazinoquinoxaline-based building blocks were incorporated into both π-conjugated dendrimers and polymers. The dendrimers were synthesized using a convergent/divergent approach whereas the donor/acceptor copolymers were synthesized via Stille cross-coupling reactions. The structurally defined dendrimers and the π-conjugated polymers were investigated with respect to their optical and electronic properties
