以4-溴-1,8-萘酐作为原料,首先合成了4-溴-N-烯丙基-1,8-萘酰亚胺,进一步合成4-苯基胺-N-烯丙基-1,8-萘酰亚胺可聚合荧光小分子。采用无皂乳液聚合法,制备苯乙烯与荧光小分子共聚微球。利用红外光谱表征了产物结构,通过扫描电镜观察了所制备的共聚物微球的外貌,利用紫外和荧光光谱测试了产物的荧光性质。结果表明,荧光小分子的最大发射波长为429nm,共聚物的最大发射波长为464nm,所得共聚物微球表面光洁。
Starting from 4-bromo-1,8-naphthalene anhydride, 4-bromo-N-allyl-1,8-naphthalimide was synthesized and 4-phenylamine-N-allyl- 1,8-Naphthalimide polymerizable fluorescent small molecule. Using soap-free emulsion polymerization, styrene and fluorescent small molecule copolymer microspheres were prepared. The structure of the product was characterized by infrared spectroscopy. The morphology of the prepared copolymer microspheres was observed by scanning electron microscopy. The fluorescence properties of the copolymer microspheres were tested by UV and fluorescence spectroscopy. The results showed that the maximum emission wavelength of the fluorescent small molecule was 429 nm, the maximum emission wavelength of the copolymer was 464 nm, and the surface of the obtained copolymer microspheres was smooth.
