Kobayashi, Eiichi published the artcileNovel conjugated polymer containing anthracene backbone: addition polymer of 9,10-diethynylanthracene with 9,10-anthracenedithiol and its properties, HPLC of Formula: 18512-55-5, the publication is Journal of Polymer Science, Part A: Polymer Chemistry (1990), 28(10), 2641-50, database is CAplus.
9,10-Diethynylanthracene (I) was prepared by alk. hydrolysis of 9,10-bis(trimethylsilylethynyl)anthracene. Another monomer, 9,10-anthracenedithiol (II), was prepared by reduction of anthracene polydisulfide. A crystalline conjugated polymer (III) of I with II was synthesized in a THF solution at 50° by UV irradiation or using radical initiators. The number-average mol. weight of the insoluble III in THF was about 20000-30000 and the soluble was about 4000. Based on the S content and IR spectrum of the insoluble III, the obtained III had an alternating structure consisting of I and II units. X-ray patterns indicate that the polymer has a layered structure. The conductivity of undoped III was 10-11 S/cm, but increased to 10-6 S/cm by doping with iodine.
