Jiang, Jian published the artcileNovel conjugated polymer containing anthracene backbone: the microstructure of polymer composed of 1,4-benzenedithiol with 9,10-diethynylanthracene and isomerization of the polymer and model compounds, COA of Formula: C18H10, the publication is Polymer Journal (Tokyo, Japan) (1990), 22(3), 274-82, database is CAplus.
In order to determine the microstructure of the polymer composed of 1,4-benzenedithiol with 9,10-diethynylanthracene, the model compounds cis– and trans-9,10-bis(phenylthiovinylene)anthracenes were prepared In comparison with the characteristic absorption peaks of vinylene in the model compounds, the microstructure of the polymer was evaluated. Regardless of the initiation mode, UV irradiation, AIBN and none, the cis contents of the polymers were 80-85%. The cis configuration of the polymer isomerized gradually to the trans one with increase of UV irradiation time. The characteristic features of the isomerization were also studied using model compounds The cis isomer of the model compound underwent irreversible isomerization to the trans one by UV irradiation In the presence of a radical source in the reaction system, both the cis and trans isomers can isomerize and reach an equilibrium state after reaction for a sufficient time. The isomerization mechanism was also discussed based on the potential energy diagram.
