  • Inventors:
    - Evanston IL, US
    Xisen Hou - Skokie IL, US
    Chenfeng Ke - Skokie IL, US
  • International Classification:
    C09B 57/00
    C09K 11/06
  • Abstract:
    Fluorescent dyes are provided. The fluorescent dyes are heterorotaxanes that include large macrocyclic rings around fluorophores and are capable of emitting solid-state fluorescence.

  • US Patent:
    20160137864, May 19, 2016
  • Filed:
    Sep 28, 2015
  • Appl. No.:
    14/867953
  • Inventors:
    - Evanston IL, US
    - Winter Park FL, US
    Chenfeng Ke - Skokie IL, US
    Roger B. Pettman - Winter Park FL, US
  • International Classification:
    C09D 11/50
  • Abstract:
    Fluorescent dyes, ink compositions comprising the dyes, methods and devices for printing the ink compositions, images printed using the ink compositions and methods for authenticating the printed images are provided. The fluorescent dyes are heterorotaxanes that include large macrocyclic rings around fluorophores and are capable of emitting solid-state fluorescence. When the heterorotaxanes are combined with encapsulating agents and competitive binding agents in aqueous solution, the resulting ink composition exhibits a complex, dynamic equilibrium that provides a tunable fluorescence emission spectrum with a non-linear response to the dye concentration.
