Assembling achiral molecules typically generates achiral domains. However, odd things can happen when the molecules are banana-or boomerang-shaped—their cores can twist out of plain to form left- or right-handed helices, which can then pack into ch

Epitaxial crystallization of isotactic poly(1-butene) (iPBu) is performed on different substrates, which help expand the range of interactive substrates used in a previous study. All three crystal forms of iPBu1, which rest on different helix and uni

Thin spin-coated films of a smectic liquid crystalline main chain polymer with an azoxybenzene as mesogen were investigated as a function of temperature and thickness. Both lateral and vertical ord...

N-Octyl-d-gluconamide (1) is known to form noncovalent quadruple helices in bulk aqueous media. Upon adsorption to mica these fibers survive; on gold they rearrange to give a head-to-tail bilayer. This is the thermodynamically most stable arrangement

High density polyethylene (PEHD) and isotactic polypropylene (iPP) blends exhibit a maximum in impact strength at a specific mixing ratio. This effect is even more pronounced if a compatibilizer is added. An explanation was found by analyzing the mor

The degree of polymerization (DPn) of poly(p-phenylene) (PPP) 3 with appendant third-generation, Frechet-type dendrons was determined as 110 after a chemical modification. This DPn is extraordinarily high and shows that the mechanistically complex Su

We demonstrate the use of tapping mode atomic force microscopy (TMAFM) for the study of liquid crystal prewetting films spreading on silicon wafers. With AFM, we are able to image the edge of the prewetting film when it spreads on the solid and to ob

The metastable phase of isotactic polypropylene (βiPP) is crystallized epitaxially on two specific nucleating agents: γ-quinacridone and dicyclohexylterephthalamide (DCHT). The resulting thin film...

Tetrakis(aminophenyl)porphyrin with four bixin side chains in statistical orientation with respect to the porphyrin plane and its zinc(II) complex produced stable colloidal solutions in water at pH 9. Cryoelectron microscopy showed spherical unilamel
