通過(guò)4-溴-1,8-萘酸酐與正己胺反應(yīng)得到了N-己基-4-溴-1,8-萘酰亞胺,并進(jìn)一步與各種噻吩的衍生物反應(yīng)合成了一系列含噻吩的新型萘酰亞胺衍生物。考察了各種目標(biāo)產(chǎn)物的產(chǎn)率、熔點(diǎn)及在各種溶劑中的溶解度,并采用1H-NMR、13C-NMR和紫外可見(jiàn)光譜對(duì)產(chǎn)物的結(jié)構(gòu)進(jìn)行表征,考察了其熒光性能。結(jié)果表明,噻吩環(huán)上不同取代造成環(huán)上吸電子性的不同以及共軛程度的不同使熒光光譜了發(fā)生移動(dòng),其中化合物2k在605 nm 處發(fā)射紅光,為所有化合物中最長(zhǎng)。這一結(jié)果能幫助我們?cè)O(shè)計(jì)基于1,8-萘酰亞胺衍生物的新的熒光材料。 [ Last edited by 張超峰 on 2012-5-7 at 16:53 ] |

| 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. |
