We synthesized two homodendrimers (A3 and B3) and two block codendrimers (A2B and AB2). We chose three hydrophilic dendron (A)-containing dendrimers and for each dendrimer, two ion-doped samples, 1 and 2, [Li+]/[EO] were 0.2 and 0.4, respectively, were prepared. The ion-doped samples from the homodendrimer (A3) were shown to be viscous amorphous liquid. While the resutls of the POM, DSC, and X-ray scattering showed that A2B-1 exhibited an interdigitated lamellar structure, whereas A2B-2 showed a bilayered columnar structure. Taking into account the hydrophilic volume fraction (f = 0.74) of A2B-2, its columnar matrix is composed of hydrophilic coils and ionic species. The AB2-1 with f = 0.47 self-organized into a bilayered columnar structure with a hydrophobic matrix. The AB2-2 with f = 0.53 revealed a bicontinuous cubic structure with Ia3d. Consequently, we can be systematically engineered as a function of the inserted ion concentration and/or hydrophilic volume fraction. |
