The effects of the casting speed and solute concentration on crystallization 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene (C8-BTBT) during meniscus-guided coating (MGC) are investigated, three morphological subregimes with increasing identified: I) an isotropic domain-like structure; II) unidirectionally aligned crystalline bands; III) a corrugated dendritic morphology. Interestingly, does...
