1,3,5-Tris(1-phenyl-1H-benzimidazol-2-yl)benzene (TPBi) is normally used as functional materials in organic light-emitting diodes (OLEDs) and the information about the solubilities of TPBi in organic solvents is crucial for the preparation of inks toward inkjet printing technology, which is considered to be a next-generation manufacturing method for OLED production. The solubilities of TPBi in 12 kinds of organic solvents, including n-hexane, cyclohexane, methanol, ethanol, isopropanol, n-butanol, acetonitrile, ethyl acetate, dimethyl sulfoxide, tetrahydrofuran, chlorobenzene, and trichloromethane, at the temperature range from 283.15 to 323.15 K and atmospheric pressure were determined based on the isothermal saturation method. The obtained solubility data were correlated by the modified Apelblat equation and the correlated results exhibited good agreement with the experimental data. The nanonization of TPBi was conducted via high gravity-assisted solvent/antisolvent precipitation processing, which showed a beneficial effect for film formation.
