Abstract
Ionic compounds comprising: (a) a cationic radical of a charge transporting compound which has one or more reactive groups; and (b) a counter anion. The ionic compound may have the following formula: The reactive functional groups on the cation allow the ionic compound to cross-link with a host charge transport compound. Such ionic compounds may have various properties, such as thermodynamic stability, hole injection/transport capabilities, electrochemical durability, and/or solubility in organic solvents that allows them to be useful in organic electronic devices. Also provided are electronic devices made using the ionic compounds of the present invention, and methods of making an electronic device.
