| Abstract: | We synthesized oligo(p-phenyleneethynylene)s and oligo(p-phenyleneethynylene)s end-capped by vinyl by Sonogashira cross|coupling reaction. Then we prepared cross-linked PPE with or without residue vinyl by radical polymerization or heat curing at 175_280 ℃ of vinyl|functionalized olgomers. Having investigated cross-linked PPE and oligomers by FTIR, WXRD and photoluminescence, we found that cross-linked PPE without residual vinyl destroys the main chain π-π stacking completely in solid state. Moreover, the wavelength of the strongest emission of these cross-linked PPE varies from 310 nm to 390 nm, so they can be used as purple/blue light|emitting materials. |
