Abstract
- Phosphorous-based organic acids (P) and diamine (M) were used to produce a supramolecular PM complex at a 2:1 molar ratio, which then formed a stable gel in dimethyl sulfoxide (DMSO) and N, N-dimethylformamide (DMF). According to SEM, the morphologies of the aggregates depended on the steric substitute of phosphorous-based organic acids and the structure of the complementary diamine.31P NMR and FTIR spectroscopies revealed that hydrogen bonding within the PM complex was the main driving force for the self-aggregation. XRD studies revealed that the two-component gelators mainly assemble into a stricter lamellar structure when increasing the rigidity of the complementary component. In contrast, the gelators with the aliphatic unit mainly assembled into a random lamellar structure and showed more possibility of deforming. As such, the results in this paper demonstrate how structure effects in two-component gel system of phosphorous-based organic acids and diamine can control self-assembly process.
