  • Paracyclophane molecules for two-photon absorption applications
    Patent number: 7232913
    Abstract: Chromophores having two-photon or other multi-photon absorptivity. The chromophores are based on a structure of four stilbenoid groups attached to a paracyclophane core, where each stilbenoid group comprises a nitrogen-containing organic group attached by its nitrogen atom to a stilbenoid arm. In particular embodiments, at least one of the stilbenoid groups includes a sulfonium, ammonium, selenium, iodonium or phosphonium moiety. The chromophores have utility as photo-polymerization initiators and two-photon fluorophores for biological imaging.
    Type: Grant
    Filed: September 28, 2004
    Date of Patent: June 19, 2007
    Assignee: The Regents of the University of California
    Inventors: Guillermo C. Bazan, Bernhard Koehler, Hadjar Benmansour, Janice W. Hong, Han Young Woo, Alexander Mikhailovsky, Hideki Gorohmaru, Shuuichi Maeda, T. Kojima, Motoyuki Shigeiwa

  • Water-soluble distyrylbenzene chromophores for applications in optoelectronic technologies
    Patent number: 7094929
    Abstract: Two-photon or multi-photon chromophores having a conjugated pi-electron system with donating groups at each end of the pi-electron system providing charge-transfer properties, and having quaternary amine groups that can enhance the solubility of the chromophore in water. In a particular embodiment, the chromophore is based on a distyrylbenzene core, with donor or acceptor groups attached to the central benzene ring.
