Abstract

original image

From single crystal to single crystal: A crystalline charge-transfer complex of the title compounds underwent topochemical polymerization through a radical mechanism under UV irradiation or upon heating. This cis-specific solid-state copolymerization of the substituted quinodimethanes required the alternating monomers in the cocrystal to tilt (see picture).
