The structure of poly(m-phenylene): a prediction from single-crystal X-ray studies of m-deciphenyl and m-undeciphenyl
Abstract
Single-crystal X-ray diffraction studies of the oligomers m-deciphenyl and m-undeciphenyl, isolated chromatographically from low molecular mass poly(m-phenylene), reveal disordered but unequivocally helical chain-structures, from which the crystal and molecular structure of poly(m-phenylene) can be directly inferred.
