Chemical Equation Presented The self-assembly of functional polythiophenes was studied by a bottom-up approach from molecule to polymer . The synthesis and the X-ray structure of 2, 5-dibromo-3-styryl and 32′,3′,4′,5′,6′-pentafluorostyryl-thiophenes revealed a supramolecular arrangement controlled by ν-ν interactions between the aromatic rings. A [2 + 2] photocyclization reaction in the solid state of (E)-1-2ν,5ν-dibromo-3ν-thienyl-2-pentafluorophenylethene triggers the formation of a rare cycloadduct comprising thiophene rings. The X-ray analysis confirmed its rctt stereochemistry. The synthesis of P3HT-b-P3ST and P3HT-b-P3STF block oligomers was achieved by a GRIM method in good yields. An indirect proof of well-defined nanostructured organization was provided by the partial photocyclization of pendant styryl moieties under UV irradiation.
