Fine‐Tuning the Microstructure and Photophysical Characteristics of Fluorescent Conjugated Copolymers Using Photoalignment and Liquid‐Crystal Ordering (Adv. Sci. 41/2024)

Patterning Polymer Chain Orientation Bringing long‐range structural ordering into otherwise disordered polymer semiconductors is long‐sought for bio‐inspired organic systems and light confinement. In article number 2407117, Yuping Shi and co‐workers developed a photoalignment technique to inscribe high‐resolution bespoke chain‐orientation patterns in large‐area extended polymer crystals that exhibit unity order parameters and remarkably anisotropic excitation energy transfer and emission.
