Significance

Thermal polymerization of monomers such as 1 produced melt- and solution-processable branched oligomers (P1) via an initial Bergman cyclization. Subsequent curing afforded network poly(arylene)s, such as P2, with high thermal stability. Further heating produced semiconductive glassy carbon in high yield.
