Paragraph 0071; 0073-0077, (2020/08/06)
The invention provides an aromatic compound containing a tetraphenylethylene structure and a preparation method and application thereof, belonging to the technical field of fluorescence sensing. The preparation method of the aromatic compound containing the tetraphenylethylene structure comprises the following steps: reacting a halogenated aromatic ring with borate under anhydrous and anaerobic conditions to obtain an aryl borate intermediate; and carrying out a SUZUKI reaction on the aryl borate intermediate and halogenated tetraphenyl ethylene to obtain the aromatic compound containing the tetraphenylethylene structure. The aromatic compound containing the tetraphenyl ethylene structure provided by the invention has a relatively large conjugated structure and a wide charge delocalizationrange, and the unique three-dimensional configuration of the aromatic compound is beneficial for obtaining a good aggregation structure, so the aromatic compound has good application prospects in thefields of sensing technologies and detection functions, is high in practicability and shows relatively high popularization and application values.

Citrate trisulfonic acid (CTSA), as a novel recyclable and eco-benign organocatalyst, was employed for the efficient and one-pot synthesis of trisubstituted imidazoles and tetrasubstituted imidazoles using aldehydes, ammonium acetate or aniline, and benzoin, benzyl, or 9,10-phenanthrenequinone under solvent-free conditions providing high to excellent yields. CTSA is easily prepared via the reaction of trisodium citrate and chlorosulfonic acid in high purity. Compared to the conventional procedures, the present method offers several advantages, including high yields, easy work-up, short reaction time, reusability of the catalyst, and simple purification of the products.
