Investigation on solvent casting films of surfactant-encapsulated clusters.
The surfactant-encapsulated cluster (SEC) composed of a hydrophobic dimethyl dioctadecyl ammonium (DODA) shell and an encapsulated hydrophilic polyoxoanion core can form casting films. The structure of the casting film is influenced by evaporation rates of organic solvent. When the casting films are prepared by slow evaporation of chloroform, the alkyl chains are considered to possess a partial interdigitation, and the interdigitated length is 1.6 nm. The casting film structure is characterized by scanning force microscopy (SFM), Fourier transformation infrared (FT-IR), wide-angle X-ray diffraction, and differential scanning calorimetry (DSC).
Toward nanodevices: Synthesis and characterization of the nanoporous surfactant-encapsulated keplerate (DODA)(40)(NH4)(2)[(H2O)(n)subset of Mo132O372(CH3COO)(30)(H2O)(72)].
We describe the spontaneous self-assembly and the superstructure of a discrete surfactant-encapsulated cluster, (DODA)40(NH4)2[(H2O)n⊂Mo132O372(CH3COO)30(H2O)72] (2, n ≈ 50), which consists of a ho...
