Patent ID: 7498084

Claim:
A macromolecular structure, comprising a hole-conducting layer and an electron-conducting layer, wherein: the macromolecular structure comprises a first hyperbranched macromolecule and a second hyperbranched macromolecule; the first hyperbranched macromolecule, the second hyperbranched macromolecule, or both of the first hyperbranched macromolecule and the second hyperbranched macromolecule has either a hole conductivity or an electron conductivity; one of the hole-conducting layer and the electron-conducting layer includes the first hyperbranched macromolecule or the second hyperbranched macromolecule; the macromolecular structure has a self-assembled structure formed by a non-covalent interaction via the first hyperbranched macromolecule or the second hyperbranched macromolecule; and the self-assembled structure is located in at least one of the hole-conducting layer, the electron-conducting layer, and an interface between the hole-conducting layer and the electron-conducting layer.
