    摘要: An electroluminescent element has an anode, a cathode, and an organic layer structure between the two electrodes. The layer structure has a luminescent zone containing 1,9-perinaphtylene-10-1null-naphthylanthracene or derivatives as dopant. The luminescent material utilized as dopant has the following structure called pNNA or pNNA derivatives: 1 Wherein: R3 R1, R2, R3, R4 are individual substituents or a group of substituents, and they may be identical or different. Each substituent is individually selected from the following groups consisting of: H, alkyl (nullR), halogen (nullX), aryl (nullAr), alkenyl (RCHnullCHnull), allyl(CH2nullCHCH2null), cyano (NCnull), isocyano (CNnull), amino (H2Nnull), tertiary amino (R2Nnull or Ar1Ar2Nnull), amide (RCONRnull), nitro (N2Onull), acyl (RCOnull), carboxyl (nullCO2H), alkoxyl (ROnull), alkylsulfonyl (RSO2null), hydroxy (HOnull) and single or fused aromatic heterocyclic rings.

    摘要: A polymerizable ligand comprising, in one embodiment, a polyaromatic compound, with a terminal functional group, non-covalently bonded to the sidewalls of carbon nanotubes. This structure preserves the structural, mechanical, electrical, and electromechanical properties of the CNTs and ensures that an unhindered functional group is available to bond with an extended polymer matrix thereby resulting in an improved polymer-nanotube composite.

    摘要: The present invention provides methods of preparing functionalized graphene nanoribbons. Such methods include: (1) exposing a plurality of carbon nanotubes (CNTs) to an alkali metal source in the presence of an aprotic solvent to open them; and (2) exposing the opened CNTs to an electrophile to form functionalized graphene nanoribbons (GNRs). The methods may also include a step of exposing the opened CNTs to a protic solvent to quench any reactive species on them. Additional methods include preparing unfunctionalized GNRs by: (1) exposing a plurality of CNTs to an alkali metal source in the presence of an aprotic solvent to open them; and (2) exposing the opened CNTs to a protic solvent to form unfunctionalized GNRs.
