Abstract

The liquid crystalline material of triply fused metalloporphyrin dimmer is prepared by incorporating hydrophilic triethylene glycol chains (TEG) and amphiphilic paraffinic side chains into the copper porphyrin dimmer. This compound forms a liquid crystal column at room temperature with excellent electron transport ability.

Abstract

A photoconductive liquid crystal (LC) with bicontinuous arrays of densely packed D and A components, tailored from amphiphilic oligothiophene-[C.sub.60] dyad is described. The results have highlighted the crucial role of the amphiphilic design both in structuring and in photoconductivity.

Abstract

A π-conjugated nanosheet comprising planar nickel bis(dithiolene) complexes was synthesized by a bottom-up method. A liquid–liquid interfacial reaction using benzenehexathiol in the organic phase and nickel(II) acetate in the aqueous phase produced a semiconducting bulk material with a thickness of several micrometers. Powder X-ray diffraction analysis revealed that the crystalline portion of the bulk material comprised a staggered stack of nanosheets. A single-layer nanosheet was successfully realized using a gas–liquid interfacial reaction. Atomic force microscopy and scanning tunneling microscopy confirmed that the π-conjugated nanosheet was single-layered. Modulation of the oxidation state of the nanosheet was possible using chemical redox reactions.

Abstract

The article presents a study on photoconductive liquid crystal (LC) with bicontinuous arrays of densely packed D and A components tailored from amphiphilic oligothiophene-C60 dyad 1Amphi with contrasting results for a nonamphiphilic reference (1Lipo). The study revealed that the molecular structures of 1Amphi and 1Lipo are identical to each other except for terminal wedges.
