Base Compound

In order to investigate the supramolecular assembly and coordination interaction of special amphiphile, a trigonal Schiff base compound with long alkyl chains was designed and synthesized, and its supramolecular assembly and interaction properties were investigated by spectral and morphological measurements. It was found that the Schiff base compound can be spread on water surface to form stable monolayer. When on the Zn(II) ions subphase, an in situ coordination can occur for all ligands. As a result, a 1:2 complex was formed for the trigonal chain Schiff base with Zn(II) ions through the coordination interaction. Due to the directionality and strong matching of coordination, two Zn(II) ions can be encapsulated into intramolecular space of the trigonal Schiff base compound.

In order to investigate the supramolecular assembly and interfacial coordination of special amphiphile, two Schiff Base compounds with alkyl chains and different azobenzene substituted groups were designed and synthesized, and their supramolecular assembly and interfacial properties were investigated by spectral and morphological measurements. It was found that the Schiff base compounds can be spread on water surface to form stable monolayer. When on the Cu(II) ions subphase, an in situ coordination can occur for all ligands. In addition, for the coordination process of C16SB-Me-Azo with Cu(II), there are obvious spectral changes for the alkyl chains. For all process, the headgroups in all amphiphiles have predominant effect in regulating the aggregation mode and spectral changes in organized molecular films.

Base Compound

In order to investigate the chiral interfacial assembly of special amphiphile, a trigonal Schiff base compound with long alkyl chains was designed and synthesized, and its supramolecular assembly and interaction properties were investigated by spectral and morphological measurements. Condensed monolayers were obtained on pure water surface, in which flat and uniform domains were obtained for the monolayers. When an anionic tetrakis(4-sulfonatonphenyl)porphine (TPPS) was added into an acidic subphase, an in situ complex formation between the trigonal amphiphile and TPPS occurred. The complex monolayers were transferred onto solid substrate and TPPS existed as J-aggregate and J-aggregate in the complex films. Due to the multisited positive charges in the spacer on acidic subphase, the complex films of trigonal amphiphile with TPPS appeared as short nanorod structures and formed two-dimensional (2D) conglomerate chiral domains.

Apparent Diameter

To date, most 3-D reconstructions of undecorated actin filaments have been obtained from actin filament paracrystal data (for refs, see 1,2). However, due to the fact that (a) the paracrystals may be several filament layers thick, and (b) adjacent filaments may sustantially interdigitate, these reconstructions may be subject to significant artifacts. None of these reconstructions has permitted unambiguous tracing or orientation of the actin subunits within the filament. Furthermore, measured values for the maximal filament diameter both determined by EM and by X-ray diffraction analysis, vary between 6 and 10 nm. Obviously, the apparent diameter of the actin filament revealed in the EM will critically depend on specimen preparation, since it is a rather flexible supramolecular assembly which can easily be bent or distorted. To resolve some of these ambiguities, we have explored specimen preparation conditions which may preserve single filaments sufficiently straight and helically ordered to be suitable for single filament 3-D reconstructions, possibly revealing molecular detail.
