  • Blue-shifted triarylamine polymer
    Patent number: 8502199
    Abstract: A semiconductive conjugated polymer comprising a first repeat unit comprising general formula I: where Ar1, Ar3, and Ar5 are the same or different and wherein each represents an optionally substituted aryl or heteroaryl group; Ar2 and Ar4 are the same or different and each represent a substituted aryl or heteroaryl group; and Ar2 and Ar4 sterically interact with one another so as to cause an increase in the bandgap of the polymer.
    Type: Grant

  • Polymers their preparation and uses
    Patent number: 7696303
    Abstract: A polymer for use in an optical device comprising a first, optionally substituted, repeat unit of formula and a second, optionally substituted, repeat unit of formula wherein each Ar and Ar? is the same or different and comprises an optionally substituted aryl or heteroaryl group and optionally a third, optionally substituted, repeat unit in a molar ratio of no greater than 5%, the third repeat unit having a formula —Ar—N(Ar)—Ar— and having a single nitrogen atom in its backbone.

  • Detection cell, a detector, a sensor, and a spectroscope using a superconductive tunneling junction
    Patent number: 5381001
    Abstract: The present invention relates mainly to a detection cell, a matrix detector using such cells, a sensor including such a detector, and a spectroscope including such a sensor. The invention provides a photon detection cell comprising a superconducting element, in particular of niobium, that is sensitive to photons of the radiation to be detected or to phonons generated by such photons, in particular by breaking Cooper pairs into quasi-particles and by means of a superconducting tunnel junction including a superconducting electrode, the cell being delimited by a plurality of spaced-apart superconducting tunnel junctions that are distributed around the periphery of the cell. The device of the invention is applicable to counting photons, and thus mainly to acquiring and processing information coming from faint radiation sources.
