This presentation will survey recent examples from our lab in which we have created conjugated polymers (CPs) composed of alternating oligo(phenylene vinylene)s and flexible segments. Our synthetic strategy utilized a Sonogashira cross-coupling polymerization to join pre-synthesized, and therefore structurally uniform, oligo(phenylene vinylenes) of 3, 5, and 7 repeat units with a tetraethylene glycol containing linker. We utilized polarization modulation fluorescence microscopy to interrogate individual polymer molecules for their conformation and electronic properties, and have found a direct link between the chromophore size and the resulting anisotropy of the polymer nanostructures.
