This chapter provides a brief summary of the available synthetic methods leading to poly( p ‐phenylene vinylene)s (PPVs), followed by a detailed discussion of the mechanism of PPV synthesis, employing the Gilch route. In the latter case, in situ‐ generated p ‐quinodimethanes are shown to be the active monomers. Spontaneously formed diradicals initiate the chain growth, and are the reason why [2.2]paracyclophanes are formed as side products. Oxygen is identified as a highly efficient molar mass‐regulating agent, and evidence is provided as to why E ‐configured halide‐bearing vinylene moieties should be perceived as being among the most critical chain defects with respect to the efficiency and durability of (opto)electronic devices based on Gilch‐PPVs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
