  • Publication number: 20240130229
    Abstract: A novel high molecular compound is provided. The high molecular compound includes a repeating unit. The repeating unit has a fluorenediyl group, a hole-transport skeleton, and an electron-transport skeleton. The hole-transport skeleton is bonded to the fluorenediyl group through a substituted or unsubstituted first arylene group. The electron-transport skeleton is bonded to the fluorenediyl group through a substituted or unsubstituted second arylene group. In an excited state, intramolecular charge transfer occurs between the hole-transport skeleton and the electron-transport skeleton.

  • Patent number: 4131644
    Abstract: Carbon fibers having excellent modulus of elasticity and tensile strength are produced in a high yield by a process wherein polybutadiene fibers are prepared by melt-spinning polybutadiene having at least 85% of vinyl structure, a melting point of at least 100.degree. C and a reduced viscosity of 0.3 to 1.2 dl/g; the fibers are then treated in a solution or suspension of a Lewis acid in an inert organic liquid, whereby the pollybutadiene is cyclized and cross-linked; the polybutadiene fibers treated as mentioned above are further treated in a melted sulphur or a sulphur-containing solution at a temperature of 170 to 300.degree. C, whereby the cyclized and cross-linked polybutadiene is dehydrogenated and aromatized; and the fibers treated as mentioned above are carbonized by raising the temperature thereof to 750.degree. C to 3000.degree. C to form carbon fibers or graphite fibers. If so desired, the ordinary carbon fibers which have been produced at 750 to 1500.degree.
