  • Patent number: 9725544
    Abstract: A ?-conjugated aromatic/heteroaromatic oligomer-containing vinyl monomer is generally provided, which can include a polymerizable group, a linker group, and a ?-conjugated aromatic/heteroaromatic side chain. The ?-conjugated aromatic/heteroaromatic side chain includes a first cyclopentadiene ring covalently attached to the linder group, a set of second cyclopentadiene rings covalently attached to the first cyclopentadiene ring, and a third cyclopentadiene ring positioned at a terminal end of the ?-conjugated aromatic/heteroaromatic side chain such that the set of second cyclopentadiene rings is positioned between the first cyclopentadiene ring and the third cyclopentadiene ring. Methods are also provided for forming a polymer via polymerizing the ?-conjugated aromatic/heteroaromatic oligomer-containing vinyl monomer, and for grafting a ?-conjugated aromatic/heteroaromatic oligomer-containing polymer onto a surface of a nanomaterial.
    Type: Grant

  • Publication number: 20140252341
    Abstract: Disclosed are a pyrrolo-pyrroledione-thiophenequinone compound as shown by formula I, a preparation process thereof and the use thereof as an organic semiconductor material. The preparation process for the compound of formula I comprises reacting NaH, an ?-bromine substituted pyrrolo-pyrroledione-thiophene oligomer as shown by formula II and malononitrile sodium salt, in the presence of catalytic Pd(PPh3)4, and then adding to the reaction system saturated bromine water to carry out an oxidation reaction, so as to obtain the compound of formula I. The compound of formula I has a good field effect performance, an electron mobility of above 0.1 cm2V?1s?1, an on/off current ratio up to 105, and is stable in air.
