两亲性萘双酰亚胺的合成及其凝胶性能

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、~(13)C 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%H_2O-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.

Synthesis and Gelation Properties of Amphiphilic Naphthalene-Diimide

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、~(13)C 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%H_2O-THF).
