Synthesis and properties of anthracene containing polyethers

Full Paper: Four poly(oxymethyleneanthrylene)s were prepared by polycondens ation of 9,10-diacetoxyanthracene (and a substituted analogue) with alpha,o mega-dibromoalkanes. Two model compounds were also synthesized by the same procedure. Although non-conjugated the polymers could be doped with iodine. The redox reaction of doping was confirmed by the changes in the electroni c and fluorescence spectra as well as by the appearance of paramagnetism an d enhanced electrical conductivity. In comparison, the model compounds coul d not be doped. Doping with iodine occurs only when the polymers are in the solid state. This state polymer effect, reported also in previous publicat ions, is explained by collective interactions of several anthracene units w ith the dopant.
