两亲性萘双酰亚胺的合成及其凝胶性能

Synthesis and Gelation Properties of Amphiphilic Naphthalene-Diimide

摘要: 以没食子酸和萘四酸酐为基本原料，通过三步反应，简单高效地合成了两个新的两亲性萘双酰亚胺类化合物（NDI-1和NDI-2）.通过IR、¹H NMR、¹³C NMR、HRMS对目标分子的结构进行了表征，并详细研究了它们在不同溶剂中的凝胶性能.结果表明：NDI-2是一种多功能凝胶因子，不仅可以在非极性溶剂（苯、甲苯、二甲苯）中，还可以在强极性溶剂（DMSO）以及含水溶剂（30% H₂O-THF）中以较低的临界成胶浓度（CGS，3.3~9.5 g/L）形成稳定凝胶.

Abstract: Two novel amphiphilic naphthalene diamide compounds (NDI-1 and NDI-2) were synthesized simply and efficiently by three-step reaction,using gallic acid and naphthalene tetraanhydride as basic materials.The structure of these amphiphilic naphthalene diamides were characterized by IR、¹H NMR、¹³C NMR and HRMS,and the gelating abilities of them in different solvents were studied in details.The results showed that NDI-2 is a versatile gelator,which can form into stable gels at a low critical gelation concentration (CGS,3.3~9.5 g/L),not only in non-polar solvents (such as benzene,toluene and xylene) but also in strong polar solvent (DMSO) and aqueous solvent (30% H₂O-THF).
