Kobayashi, Eiichi published the artcileNovel conjugated polymer containing anthracene backbone: competitive addition polymerization of dithiol monomers to diethynyl monomers and relative reactivity, SDS of cas: 18512-55-5, the publication is Polymer Journal (Tokyo, Japan) (1990), 22(2), 146-52, database is CAplus.
Competitive addition polymerizations of 9,10-anthracenedithiol (I), 4,4′-biphenyl-dithiol(II), and 1,4-benzenedithiol (III) to 9,10-diethynylanthracene (IV), 4,4′-diethynylbiphenyl (V), and 1,4-diethynylbenzene (VI) were carried out in THF at 50° by UV irradiation under a nitrogen atm., and the relative reactivities of the monomers were discussed on the basis of composition anal. for the obtained polymers. To the dithiol monomers, the relative reactivities of the diethynyl monomers were in the order of IV > V > VI. The relative reactivities of dithiol monomers to the diethynyl monomers were in the order of I > II > III. This indicated that the more the monomer conjugation, the higher was the relative reactivity. The high reactivities of anthracene derivatives would be caused from stabilization of the intermediate carbon radical and thio radical by its high conjugation system.
