Synthesis, spectroscopy, and electrochemistry of ionic hosts for organic electronics

We report on charge- and ion-transport ionic hosts made from an imidazolium-cation-modified aryl-1,2,4-triazole, phosphineoxide-carbazole, and phosphineoxide. The hosts are white solids that have short-wavelength absorption cut-off at <355 nm (high-energy optical gap of >28,200 cm(-1)) and that exhibit oxidation at <1.44 V and reduction at >(-2.75) V against ferrocene with a wide redox gap of >3.9 V.
