On page 1617 , Athmen Zenati and Soulighothai Thammalangsy discuss well‐controlled molecular weight ABC‐type azo‐triblock copolymers (TBC). These coploymers, consisting of poly(CAEMA) and poly(DOPAM) as hard blocks and central poly(MMA) as a soft block with identical lengths, were self‐assembled into a well‐defined lamellar nanostructure with domain spacing of about 35 nm, evidenced by AFM and GISAXS analysis. The microphase‐separated lamellar nanostructure in the thin TBC films was generated by the orientation and lateral ordering of the TBC domains occurring by the degree of swelling using the mixed solvent comprising cyclohexane and THF. Thus, this newly designed TBC holds promise for nanotechnological applications such as nanostructured membranes and lithographic nanotemplates. (DOI: 10.1002/pola.29025 )
