<p>PROBLEM TO BE SOLVED: To provide a cross-linkable ionic compound which can be used in an electronic device such as an organic light-emitting device (OLED).SOLUTION: An ionic compound comprises: (a) a cationic radical of a host charge transport compound which has one or more reactive groups; and (b) a counter anion. The reactive functional groups on the cation allow the ionic compound to cross-link with the host charge transport compound. Such an ionic compound may have various properties, such as thermodynamic stability, hole injection/transport capability, electrochemical durability, and/or solubility in an organic solvent that allows the compound to be useful in an organic electronic device. Also provided are an electronic device made by using the ionic compound, and a method of making the electronic device.</p> |
