Abstract

Crystal structure of an aromatic polysulfones containing biphenylene units was elucidated using diffraction simulation technique extracted from X-ray data and interfaced with computational modeling. The chain conformations and configurations were derived from a synthesized oligomer and several analogous structure of past studies. It was found that the polymer adopt an orthorhombic Cmcm with the adjacent aromatic rings attached to the sulfone linkage orthogonal to each other whilst the biphenylene unit are coplanar. The chain conformation and crystal systems are consistent with the analogous polymer containing wholly uniphenylene unit.
