Molecular bottlebrushes are highly tunable molecular scaffolds which provide interesting opportunities for creating nanostructured materials via self-assembly. Here, precision synthesis, characterization and nanoscale assembly of molecular bottlebrushes containing randomly distributed poly(3-hexylthiophene) (P3HT) and poly(D,L-lactide) (PLA) are presented. We demonstrate the importance of end-group control in macomonomer preparation that manifests an unusual aggregation behavior of bottlebrushes mediated by residual P3HTs. Our studies also show that composition and side chain length of bottlebrushes can be used to tailor the morphology and nanoscale porosity of thin films, providing a potentially useful route to generating nanostructures for optoelectronic devices. |
