  • Publication number: 20170287638
    Abstract: An electro-polarizable compound has the following general formula: Core1 is an aromatic polycyclic conjugated molecule having two-dimensional flat form and self-assembling by pi-pi stacking in a column-like supramolecule. R1 are electron donor groups connected to Core1 and R1? are electron acceptor groups connected to Core1, m is number of acceptor groups R1, m? is a number of donor groups R?. The numbers m and m? are equal to 0, 1, 2, 3, 4, 5 or 6, but both m and m? are not both equal to 0. R2 is a substituent comprising one or more ionic groups connected to Core1 directly or via a connecting group; a number p of ionic groups R2 is 0, 1, 2, 3 or 4. The fragment marked NLE has a nonlinear effect of polarization. Core2 is a self-assembling electro-conductive oligomer, a number n of the such oligomers is 0, 2, or 4. R3 is a substituent comprising one or more ionic groups connected to Core2; a number s of the ionic groups R3 is 0, 1, 2, 3 or 4.

  • Patent number: 9260655
    Abstract: Quantum-dot binding ligands with easy to synthesize alkyl-acids are provided. The quantum-dot binding ligands include a multiplicity of carboxy binding ligands in combination with an alkyl backbone, and optionally a solubilizing group. The ligands and coated nanostructures of the present invention are useful for close packed nanostructure compositions, which can have improved quantum confinement and/or reduced cross-talk between nanostructures.
