We have studied the behavior of a gemini surfactant, the double chained dodecyl ammonium bromide or 12-2-12, at the surface of aqueous solutions and at room temperature. We have measured the kinetics of adsorption and the equilibrium surface tension.

Two series of hydrogen-bonded liquid-crystalline ferrocenes have been prepared by reacting ferrocene derivatives carrying a carboxylic acid function and two flexible alkyl chains (containing n = 8, 10, or 12 carbon atoms) with stilbazoles bearing a f

The dispersion of highly hydrophobic carbon materials such as carbon nanotubes in biological media is a challenging issue. Indeed, the nonspecific adsorption of proteins occurs readily when the nanotubes are introduced in biological media; therefore,

Hydrophobically coated gold nanoparticles have been inserted in swollen surfactant lamellar phases. Insertion of the gold nanoparticles is observed only above a critical hydrophobic thickness that depends on the particle size. Such a system can thus

Two different cubic phases in pure (Ia3d cubic space group) and mixed (Im3m cubic space group) thermotropic carboxylic acids are observed by optical microscopy. In unpolarized light, the presence of the cubic phases is identified unambiguously by the

The time evolution of the fluorescence and the photoinduced absorption spectra of four triarylpyrylium cations, differing in the number of dodecyl chains attached to the chromophore, was studied by means of femtosecond fluorescence upconversion and p

Dimers formed by triarylpyrylium tetrafluoroborates in toluene and polystyrene were studied at room temperature by nanosecond flash photolysis. The time evolution of the differential absorption spectra observed for toluene solutions was interpreted i

Intercalation of triarylpyrylium salts into the MnPS3 layered phase has been achieved. The formation of J-aggregates in the interlayer space is suggested on the basis of UV–VIS absorption and emission spectroscopy experiments. The extended dipole m

Dithiolium salts, with amphipathic character, are compounds of choice for investigations of the influence of an ionic feature upon mesomorphic properties. In this way, salts bearing a branched chain have been studied by SAXS. In spite of their rod-li

The present paper deals with dialkylamino 2,4,6-triaryl pyrylium tetrafluoroborates studied in solution at room temperature. It is intended to clarify the dimerisation process described previously. The photophysical properties of the didodecylamino d
