In this contribution, we have investigated the role of side-chain composition and regioregularity on the single-polymer chain anisotropy of poly-chromophore conjugated polymers (CPs) composed of alternating oligo(phenylene vinylene)s and flexible segments.  We detail our synthetic strategies to prepare regioregular and regiorandom (2-methoxy-5-(2-ethylhexyl)-1,4-phenylenevinylene) oligomers (MEH-PPV) as well as bis(2,5-ethylhexyl)-PPV oligomers with hydrogen bonding components such as carboxylic acid and urea functionalities.  We describe our new synthetic strategies to polymerize the hydrogen-bonding oligomers into poly-chromophore structures as well as the resulting single-polymer morphology.
