A complementary guest induced morphology transition in a two-component multiple H-bonding self-assembly.


An oligo(p-phenylenevinylene) (OPV) dimer, whose OPV units are capped on their end by monotopic melamine hydrogen-bonding units, self-assembles in methylcyclohexane to form flexible fibrous nanostructures, which are transformed into rigid nanostrips upon adding ditopic cyanurates and reconverted to nanofibers upon adding a m-xylylene-linked bismelamine.
