N2 - Alkyl-substituted polyheterocycles (cf. poly(3-alkylthiophene) and poly(N-alkylpyrrole)) do not form true monomol. films at the air-H2O interface, due to lack of the required hydrophobic-hydrophilic balance. The authors designed and synthesized 2 new semi-amphiphilic alternating (AB) heterocyclic copolymers via a Stille coupling route, to study their film forming properties at the air-H2O interface, as inferred through surface pressure-area isotherms and Brewster angle microscopy. The copolymers I and II possess a N-alkylpyrrole unit, alternated with phenylene and benzothiadiazole units, resp. While copolymer-I formed a stable multilayer stack, copolymer-II forms a monomol. monolayer, at the air-H2O interface. The Langmuir film of copolymer-II could also be transferred layer-by-layer onto a substrate by vertical dipping method
