Excellent control of the thin‐film microdomain orientation of lamellar‐ (LAM) and cylinder‐ (CYL) forming ultrahigh molecular weight block copolymers has been obtained over a large area via directional solidification of a crystallizable solvent. 3D optical imaging of the microdomains via laser scanning confocal microscopy (see figure) directly show an intriguing orientation of the intermaterial dividing surfaces (IMDSs).
