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.

1,3,5-三(1-苯基-1 H-苯并咪唑-2-基)苯在有机溶剂中纳米分散体的溶解度和溶解度模型

1,3,5-三(1-苯基-1 H-苯并咪唑-2-基)苯 (TPBi) 通常用作有机发光二极管 (OLED) 中的功能材料以及有关 TPBi 在有机中的溶解度的信息溶剂对于制备用于喷墨打印技术的墨水至关重要，喷墨打印技术被认为是 OLED 生产的下一代制造方法。TPBI的12种有机溶剂，包括溶解度Ñ正己烷，环己烷，甲醇，乙醇，异丙醇，Ñ丁醇、乙腈、乙酸乙酯、二甲亚砜、四氢呋喃、氯苯和三氯甲烷，温度范围为283.15～323.15 K，常压下采用等温饱和法测定。所得溶解度数据通过修正的 Apelblat 方程进行关联，关联结果与实验数据吻合良好。TPBi的纳米化是通过高重力辅助溶剂/反溶剂沉淀处理进行的，这对成膜显示出有益的效果。
