[求助] 翻译成英语 帮帮忙啊

通过4-溴-1,8-萘酸酐与正己胺反应得到了N-己基-4-溴-1,8-萘酰亚胺,并进一步与各种噻吩的衍生物反应合成了一系列含噻吩的新型萘酰亚胺衍生物。考察了各种目标产物的产率、熔点及在各种溶剂中的溶解度,并采用1H-NMR、13C-NMR和紫外可见光谱对产物的结构进行表征,考察了其荧光性能。结果表明,噻吩环上不同取代造成环上吸电子性的不同以及共轭程度的不同使荧光光谱了发生移动,其中化合物2k在605 nm 处发射红光,为所有化合物中最长。这一结果能帮助我们设计基于1,8-萘酰亚胺衍生物的新的荧光材料。

N-hexyl- 4-bromo-1,8-naphthalimide was synthesized from 4-bromo-1,8-naphthalene anhydride and n-hexylamine, and then, it can be synthesized new naphthalimide derivatives including thiophene with some thiophene derivatives. The yield of the target product, melting point, and the solubility in all kinds of solvent were investigated. The structure of products were characterized through 1H-NMR, 13C-NMR, and UV-vis. The results show that fluorescence spectrums were shifted, which attributing to the different the attraction of electrons for different replace of thiophene ring and different extent of conjugation. And, the 2k compound reflet red light,which is the longest light in all compunds  The result is benefit to design a new fluorescent material based 1, 8-naphthalene imide derivatives.
