A facile approach to synthesize poly(benzoxazole-co-imide)s without thermal rearrangement at high temperature is proposed. Poly(benzoxazole-co-imide)s with improved mechanical and solution-processable properties were prepared through polycondensation of 4

The present invention relates to a method for preparing a 2-aminobenzoxazole compound. Comprising the following steps: (1) condensation reaction: taking o-aminophenol and nitrobenzoyl chloride compounds as raw materials, synthesizing amide intermediates in an alkaline solution system. The highly selective double-base combination system does not react with the raw material and can neutralize the acid gas generated by the reaction; (2) Cyclization reaction: acid is added to the condensation reaction solution as a catalyst, and 2-nitrobenzoxazole compounds are generated after dehydration. The solid super acid catalyst used is efficient and easy to separate and recycle; (3) hydrogenation hydrogenation reaction: 2-nitrobenzoxazole compounds are catalyzed to obtain 2-aminobenzoxazole compounds. The bi-alkali system and solid super acids used in the present invention are highly selective, product quality and yield are high. The operation is safe and simple, the raw material cost is low, in line with the green and environmentally friendly production concept, which is conducive to industrial production.

The benzoxazole derivative gelator 1 forms a stable DMF/toluene cosolvent gel with dramatically enhanced fluorescence emission compared to its mother solution. The translucent colorless gel was changed to a solution with strong greenish fluorescence in th

2-(aryl)-benz(ox, thi, imid)azoles are prepared by reacting an aromatic aldehyde with hydroxylamine to form an aromatic aldehyde oxime, halogenating the oxime to form an aromatic hydroxamoyl halide, and then reacting this halide with certain aromatic amine compounds. The products may be nitrated and then reduced to form the corresponding diamines, which are useful in making PIBX polymers.
