Nanostructured morphologies and topologies of π-conjugated polymers from thermally reactive polymer blends

Nano-and microstructured architectures of pi-conjugated polymers (see figure) are obtained by solution-casting blends of poly(methyl methacrylate) (PMMA) and a conjugated polymer bearing solubilizing tetrahydropyranyl groups followed by thermally induced, solid-phase deprotection of the conjugated polymer and subsequent dissolution of PMMA.
