  • Tetracationic cyclophanes and their use in the sequestration of polyaromatic hydrocarbons by way of complexation
    Patent number: 9290495
    Abstract: Novel tetracationic cyclophanes incorporating ?-electron poor organic compounds into their ring structures, as well as methods of making the cyclophanes, are provided. The cyclophanes are able to form electron donor-acceptor complexes with a variety of polyaromatic hydrocarbons (PAHs) ranging in size, shape, and electron density. Also provided are methods of using the cyclophanes in the sequestration of PAHs in liquid or gaseous samples, the separation of PAHs from liquid or gaseous samples, the detection of PAHs in liquid samples, and the exfoliation of graphene via pseudopolyrotaxane formation.
    Type: Grant
