All‐Conjugated, Rod‐Rod Block Copolymers‐Generation and Self‐Assembly Properties

Abstract: Based on their rigid-rod structure all-conjugated, rod-rod block copolymers show a preferred tendency to self-assemble into low-curvature vesicular or lamellar nanostructures independent from their specific chemical structure and composition. This unique and attractive behaviour is clearly illustrated in a few examples of such all-conjugated block copolymers. The resulting nanostructured heteromaterials may find applications in electronic devices or artificial membranes.

“…Scherf and co‐workers prepared two block‐copolymer derivatives with a rod‐rod structure. In this example, the polythiophene‐block‐polyfluorene were composed of a similar polyalkylfluorene block (PF2/6) and a polythiophene block functionalized with either a phosphonic ester side group (P3PHT) or a cationic side group (P3AHT) (Scheme ) 49, 50. In case of the non‐charged PF2/6‐ b ‐P3PHT, progressive addition of water to a THF solution of the polymer led to the formation of vesicles via a two‐step process.…”

“…This process is called Förster Resonant Energy transfer (FRET) . In electroluminescent devices, it is possible to exploit FRET to tune the color of the emitted light using an active layer which includes several materials with different proper optical gaps . To provide an efficient technique for internal color conversion, polymer–polymer and polymer–dye blends have been also shown to lead to a significant improvement in photoluminescence (PL) and electroluminescence (EL) quantum efficiencies .…”

“…As a result, these materials also offer significant opportunities in a number of fundamental areas. For example, the self‐assembly of fully conjugated block copolymers affords structures with low curvature due to the reduced coiling ability and long persistence length of conjugated polymers leading to preferential formation of large vesicles or lamellae in solution or the solid state, respectively . While these properties may limit access to more complex nanostructures such as bicontinuous or cylindrical morphologies, fully conjugated block copolymers have the distinct advantage that the entire polymer is semiconducting and can be electrically conductive.…”
