  • Patent number: 10662282
    Abstract: A graphene nanoribbon has a chiral edge to which a dicarbimide structure is bonded. The dicarbimide structure is an electron-withdrawing group. The width and band gap of the graphene nanoribbon are controlled by a precursor molecule used for a polymerization reaction. Furthermore, n-type operation of the graphene nanoribbon is realized by the dicarbimide structure. In addition, with the graphene nanoribbon, an increase in ribbon length and suppression of a polymerization defect by the stabilization of a reaction intermediate of the precursor molecule, as well as improvement in orientation are realized by the dicarbimide structure.

  • Patent number: 8617724
    Abstract: A polymer compound that, when used for fabrication of a light emitting device, results in an excellent luminance lifetime for the obtained light emitting device. A polymer compound comprising a constitutional unit represented by formula (1). (In the formula, R1 and R2 each independently represent an unsubstituted alkyl group. R3 and R4 each independently represent a group other than an unsubstituted alkyl group. R5 and R6 each independently represent an unsubstituted or substituted alkyl, unsubstituted or substituted alkoxy or unsubstituted or substituted aryl group. The letters a and b each independently represent an integer of 0-4. The letters c and d each independently represent an integer of 0-3. When multiple R3, R4, R5 and R6 groups are present, they may be the same or different.

  • Patent number: 8586670
    Abstract: A latex of a chloroprene polymer formed from one or more monomers comprising 2-chloro-1,3-butadiene as the main monomer ingredient, characterized in that the solid matter in the polymer latex has a gel content less than 3 mass %, the solid matter in the polymer latex includes a tetrahydrofuran-soluble component having a weight-average molecular weight of from 550,000 to 1,100,000 and a molecular-weight distribution (Mw/Mn) of from 2.0 to 3.1, and the dried solid matter in the polymer latex has a crystallization rate (R) represented by hardness increase at ?10° C. (R is the time required for initial hardness (time=0) to increase by 30 points at ?10° C. as measured according to JIS-K6301) less than 60 minutes. The chloroprene polymer latex has an excellent balance among initial bond strength, contact adhesion, and water resistance. This latex is useful as an adhesive and can be used in applications where heat resistance of 60° C. or higher, initial bond strength, and contact adhesion are required.
