  • Controlling the isomerization rate of Azo-BF2 switches using aggregation
    Patent number: 10239893
    Abstract: Provided herein are photochromic organic compounds of Formula I or Formula II, which are useful as molecular switches capable of being triggered via a cis/trans isomerization process. Methods of using the molecular switch compounds to form photopharmaceutical compounds that may be used to provide selective spatiotemporal activation of pharmaceutical agents are also disclosed.
    Type: Grant
    Filed: October 11, 2016
    Date of Patent: March 26, 2019
    Assignee: THE TRUSTEES OF DARTMOUTH COLLEGE
    Inventors: Ivan Abrahamian, Russell P. Hughes, Yin Nelson, Hai Qian
