Water Gelation of an Amino Acid‐Based Amphiphile

Published: April 2006

AbstractThe water immobilization by a simple amino acid‐containing cationic surfactant was investigated. A variety of techniques, such as 1H NMR spectroscopy, circular dichroism (CD), steady‐state fluorescence spectroscopy, and field‐emission scanning electron microscopy (FESEM) were applied to determine the formation and architecture of the hydrogel. The new gelator with a minimum gelation concentration (MGC) of 0.3 % w/v shows prolonged stability and a low melting temperature (39 °C). 1H NMR experiments revealed that intermolecular hydrogen bonding between the amide groups and π–π stacking of the indole rings are the two regulating parameters for gelation. Furthermore, fluorescence studies with 8‐anilino‐1‐naphthalenesulfonic acid (ANS) as the probe indicate the participation of hydrophobicity during gelation. The luminescence study using both ANS and pyrene, along with FESEM results, indicate a critical concentration, well below the MGC, at which fibres begin to form. These cross‐link further to give thicker fibers, leading to the formation of a hydrogel (0.3 % w/v). This new hydrogelator expresses high supramolecular chirality, as evidenced by the CD spectra. In addition, the gelator molecule was found to be nontoxic up to a concentration of 4 mM (0.2 % w/v). The high supramolecular chirality, prolonged stability, low melting point, and biocompatibility of the molecule make it a focus of chemical and biological interest.
Kinetic Study of Thermal Z to E Isomerization Reactions of Azobenzene and 4‐Dimethylamino‐4′‐nitroazobenzene in Ionic Liquids [1‐R‐3‐Methylimidazolium Bis(trifluoromethylsulfonyl)imide with R=Butyl, Pentyl, and Hexyl]

AbstractThermal Z to E isomerization reactions of azobenzene and 4‐dimethylamino‐4′‐nitroazobenzene were examined in three ionic liquids of general formula 1‐R‐3‐methylimidazolium bis(trifluoromethylsulfonyl)imide (R=butyl, pentyl, and hexyl). The first‐order rate constants and activation energies for the reactions of azobenzene measured in these ionic liquids were consistent with those measured in ordinary organic solvents, which indicated that the slow isomerization through the inversion mechanism with a nonpolar transition state was little influenced by the solvent properties, such as the viscosity and dielectric constant, of ionic liquids. On the other hand, the rate constants and the corresponding frequency factors of the Arrhenius plot were significantly reduced for the isomerization of 4‐dimethylamino‐4′‐nitroazobenzene in ionic liquids compared with those for the isomerization in ordinary organic molecular solvents with similar dielectric properties. Although these ionic liquids are viscous, the apparent viscosity dependence of the rate constant could not be explained either by the Kramers–Grote–Hynes model or by the Agmon–Hopfield model for solution reactions. It is proposed that the positive and the negative charge centers of a highly polar rotational transition state are stabilized by the surrounding anions and cations, respectively, and that the ions must be rearranged so as to form highly ordered solvation shells around the charge centers of the reactant in the transition state. This requirement for the orderly solvation in the transition state results in unusually small frequency factors of 104–107 s−1.
