The control of semi‐crystalline polymers in thin films and in micrometer‐sized patterns is attractive for (opto‐)electronic applications. Electro‐hydrodynamic lithography (EHL) enables the structure formation of organic crystalline materials on the micrometer length scale while at the same time exerting control over crystal orientation. This gives rise to well‐defined micro‐patterned arrays of uniaxially aligned polymer crystals. This study explores the interplay of EHL structure formation with crystal alignment and studies the mechanisms that give rise to crystal orientation in EHL‐generated structures.
