Conjugate rods, lateral chains

As far as the criterion for sectioiung this review article is concerned, it is not straightforward. For conveiuence, we will review 1-D assemblies of molecular rods in terms of molecular architecture. We classify rod assemblers into six molecular categories (1) rod-coil molecifles, (2) macrocyclic molecules, (3) dendron-rod-coil molecules, (4) dumbbell-shaped molecules, (5) wedge-typed molecules, and (6) conjugate rods with lateral chains. We will describe biomimetic or bioconjugate amphiphiUc rods in the last section. [Pg.71]

Modified conjugated rod segments with lateral chains can be rod building blocks that self-assemble into a variety of supramolecular one-dimensional fibers and related structures. Furthermore, if rod segments are composed of electro-optically active conjugate moieties, the self-assembled nanostructures would provide interesting supramolecular platforms for versatile functional materials [12,61,62]. [Pg.89]

Tschierske and coworkers reported on new complex liquid crystalline phases of polyphilic block molecules or their metal complex [91-93]. These triblock rod-coil molecules consist of a rod-like p-terphenylene unit, and two hydrophobic alkyl chains at both ends of the rod, and oligo(ethylene glycol) with a terminal carbohydrate unit at a lateral position of the rod [94]. Depending on the size of the hydrophilic and hydrophobic segments, a series of unusual liquid crystalline phases were detected (Fig. 18). When the carbohydrate unit is directly conjugated to the rod building block, a simple smectic (Sa) phase was observed. In this liquid crystalline phase, the molecules are... [Pg.89]
