In this work, the conformational analysis of poly(3-hexylthiophene) in dilute solutions was performed using a series of polymer homologues in a wide range of molecular weights. The projection of the monomer unit in the direction of the main polymer chain (λ = 0.37 nm) was determined experimentally for the first time. The equilibrium rigidity (А = 6.7 nm) and hydrodynamic diameter of the polymer chain (d = 0.6 nm) were also quantified.
