Interactive crystallization

As already mentioned in Section 1.1, chemists regard molecular crystals as supermolecules. This is fully justihed since molecules are built by connecting atoms through covalent bonds and crystals are built by connecting molecules with inter-molecular interactions. Crystal engineering can be dehned as the understanding of...

Controlled assemblies consisting of the binding of Au NPs to other Au NPs or nanomaterials are usually induced in the solution phase and can be driven through covalent bond formation, electrostatic interactions, crystallization, hydrophobic or van der Waals interactions, and so on. 

The determination of crystal structures by X-ray crystallography provides precise and unambiguous data on intermolecular interactions. Crystal engineering has been defined by Desiraju as the understanding of intermolecular interactions in the context of crystal packing and in the utilization of such knowledge in the design of new solids with desired physical and chemical properties. ...

Blend films of poly(L-lactide) (PLLA) and poly(vinyl alcohol) (PVA) were synthesized. The component interaction, crystallization behavior, and miscibility of these blends were studied by solid-state NMR. ... 

The reactions between K3[MoCl6] and various thiols yield dimeric or polymeric complexes of uncertain stoichiometry, thought to be [Mo2Cl4(SR)2(H20)3] or [Mo4Cl7(SR)5(H20)7], with magnetic moments which indicate considerable metal-metal interaction. Crystal structures...

Figure 10.8 Schematic illustration showing the possible morphology formation in crystaUine-crystaUine diblock copolymers by two kinds of crystallization. The upper route represents two-step crystallization, whereas the lower route shows simultaneous crystallization, where an interactive crystallization is usually observed, a-d indicate driving factors for the morphology formation.
