• The synthesis of four amphiphilic thieno[3,4-c]pyrrole-4,6-dione (TPD)-based alternating copolymers and their behavior at the air–water interface are reported. Homogeneous and stable monolayers of TPD-based copolymers were prepared. Brewster angle microscopy (BAM) was utilized to characterize the morphology and topography of these Langmuir films. UV–vis absorption spectroscopy as well as atomic force microscopy has revealed a regular transfer of some copolymers on glass substrates. It was possible to obtain homogeneous Langmuir–Blodgett films of up to 30 layers. Infrared dichroic measurements revealed an edge-on orientation. These Langmuir–Blodgett films made of conjugated polymers are therefore good candidates for organic field-effect transistors (OFETs).
