  • Fullerene derivatives and their applications in organic photovoltaics
    Patent number: 9637384
    Abstract: The present invention relates to new fullerene derivatives of formulae 1a-d, 2 and 3: method of synthesizing said derivatives, and applications thereof in organic photovoltaics, e.g., organic solar cells. In particular, the fullerene derivatives of the present invention are soluble in non-halogenated solvents such that an environmental-friendly and low-cost fabrication method for industrialization of solar cell based on the new fullerene derivatives is provided. An ink formulation for forming a thin film on a substrate of organic photovoltaics comprising at least one of the fullerene derivatives of the present invention is also provided. Greater than 3% power conversion efficiency of the organic solar cells (area=0.16 cm2) formed based on the fullerene derivatives of the present invention with less pollution and lower cost in fabrication can be achieved in the present invention.
    Type: Grant
    Filed: July 14, 2015
    Date of Patent: May 2, 2017
    Assignee: NANO AND ADVANCED MATERIALS INSTITUTE LIMITED
    Inventors: Wing Leung Wong, Lai To Leung, Liang Zhang, Chi Mei Chow, Haojun Zhu, Lai Fan Lai, Kwok Keung Paul Ho
  • Conductive and photosensitive polymers
    Patent number: 9583711
    Abstract: The present invention relates to newly functionalized polythiophenes and the syntheses thereof. The present invention also demonstrates that the new polythiophenes and their derivatives are suitable for fabricating organic light emitting diodes (OLEDs), light emitting diodes (PLEDs), organic photovoltaic devices (OPVs) and conducting polymers for printed electronic devices.

  • Luminescent protein staining
    Patent number: 8318498
    Abstract: The present invention relates to the use of cyclometalated iridium complexes for detecting poly(amino acids) including peptides, polypeptides, and proteins. Poly(amino acids) are detected in solution, in electrophorectic gels, and on solid supports, including blots. The method of the present invention is rapid, highly sensitive, and extremely facile.
