Rod-coil molecules contain a rigid and conjugated aromatic rod segment with a flexible and aliphatic coil part. Driven by anisotropic packing of the rod segment, they self-assemble in a solvent selective to the coil to form intriguing nanostructures that cannot be achieved by conventional self-assembly of coil-coil type molecules. However, the inherently poor solubility of the rod segment limits increasing its size and access to more diverse morphologies with control over size in the wider range. Here, we report synthesis of rod-coil molecules containing hydrophobic and hydrophilic branched coils. Their self-assembling morphologies will be discussed to establish structure-property relationship.
