Termination of conjugation in linear polymeric chains of heteroatoms with unshared electrons

  • 21 Accesses


  1. 1.

    The electron spectra of 4,4′-diacetyldiphenyl oxide, 4,4′-diacetyldiphenyl sulfide and of the polyazines obtained from them were taken, and also of the 4,4′-diacetyldiphenyl ethers of ethylene glycol and diethylene glycol.

  2. 2.

    Oxygen and sulfur destroy the conjugation between phenyl rings.

  3. 3.

    The electrical conductivities of a number of diketones as a function of the temperature were measured, and it was shown that high activation energies of the conductivity are due to the presence of terminating heteroatoms.
