摘要:
We report on the synthesis and self-assembly of two novel types of hydrazide derivatives, e.g. 1, 4-bis[(3,4,5-trialkoxyphenyl)-dihydrazide]-2,5-diethylphthalate (C-Tn, n=7, 10, 12 and 16) and N', N'-bis[3,4,5-tris(dodecyloxy)benzamido]-pyromellitic diimide (BI-C-T12). They were confirmed to exhibit strong gelation ability in several apolar organic solvents, such as benzene, 1,2-dichloroethane and chloroform. SEM images of the xerogels revealed that the gels consist of twist fibrous aggregates. Both FT-IR and H-1 NMR studies confirmed that the intermolecular hydrogen bonding and van der Waals interactions were the major driving forces for the self-assembly of the molecules during gelling.
