Structural study of compounds modelling elementary polymer units, 4.† Molecular and crystal structures of three isomers of 4,4′-bis(x-hydroxyphenoxy)octafluorobiphenyl
Macromolecular Chemistry and Physics
The paper presents an X‐ray study of the isomers 4,4′‐bis(2‐hydroxyphenoxy)‐, 4,4′‐bis(3‐hydroxyphenoxy)‐, and 4,4′‐bis(4‐hydroxyphenoxy)octafluorobiphenyl, which are used as monomers in the synthesis of polyarylates. The molecular packing in crystals is characterized by intermolecular H‐bonds, donor‐acceptor and stacking interactions between the benzene rings of adjacent molecules, which results in considerable distortion of the molecular geometry. Notably, bending of biphenyl fragments accompanied by distortion of benzene ring planarity was observed, along with unusual conformations of oxydiphenylene fragments and distortions of bond angles at ipso‐carbon atoms bonded to ether oxygen atoms.
