Functional Polymers: Disubstituted Polyacetylene Derivatives: Synthesis and Electroluminescent Properties

S.-H. Yang, C.-H. Huang, C.-H. Chen, and C.-S. Hsu*

C.-S. Hsu and coworkers present the synthesis of a series of disubstituted polyacetylenes containing multi-fluorophenyl and cyclohexylphenyl side groups. The effect of the number and substitution position of these fluorine atoms on energy levels and luminescent efficiency are examined. The device performance can be promoted by blending a hole transporting material into the disubstituted polyacetylene (with the difluorophenyl group (PDPA-2F)) as the active layer or by using a light-emitting copolymer in which the PDPA-2F is copolymerized with a carbazole group (PDPA-2Fcab). The synthesized PDPA-2Fcab demonstrates the best performance of polyacetylene derivatives used as light emitting materials so far.
