“…The confinement in 1D nanochannels poses severe restrictions to the geometry of the guests: to meet such requirements, molecules may deform spectacularly. Changing conformation is rather easy for methylviologen, or cyanine dyes: they have a single bond, around which the rigid parts of the molecule may rotate, in order to better fit in the channels. What it is indeed surprising, is that also fully π‐conjugated chromophores such acridine‐,,, xanthene‐, and BODIPY dyes, may exhibit unexpectedly large fluctuations from their gas‐phase planar structure (see Figure ).…”

Empty spaces are abhorred by nature, which immediately rushes in to fill the void. Humans have learnt pretty well how to make ordered empty nanocontainers, and to get useful products out of them. When such an order is imparted to molecules, new properties may appear, often yielding advanced applications. This review illustrates how the organized void space inherently present in various materials: zeolites, clathrates, mesoporous silica/organosilica, and metal organic frameworks (MOF), for example, can be exploited to create confined, organized, and self-assembled supramolecular structures of low dimensionality. Features of the confining matrices relevant to organization are presented with special focus on molecular-level aspects. Selected examples of confined supramolecular assemblies - from small molecules to quantum dots or luminescent species - are aimed to show the complexity and potential of this approach. Natural confinement (minerals) and hyperconfinement (high pressure) provide further opportunities to understand and master the atomistic-level interactions governing supramolecular organization under nanospace restrictions.

The effect of pressure on open-framework silicates: elastic behaviour and crystal–fluid interaction

2017

View full text Add to dashboard Cite

The elastic behaviour and the structural evolution of microporous materials compressed hydrostatically in a pressure-transmitting fluid are drastically affected by the potential crystal-fluid interaction, with a penetration of new molecules through the zeolitic cavities in response to applied pressure. In this manuscript, the principal mechanisms that govern the P-behaviour of zeolites with and without crystal-fluid interaction are described, on the basis of previous experimental findings and computational modelling studies.When no crystal-fluid interaction occurs, the effects of pressure are mainly accommodated by tilting of (quasi-rigid) tetrahedra around O atoms that behave as hinges. Tilting of tetrahedra is the An overview of the intrusion phenomena of monoatomic species (e.g., He, Ar, Kr), small (e.g., H 2 O, CO ) and complex molecules, along with the P-induced polymerization phenomena, (e.g., C 2 H 2 , C 2 H 4 , C 2 H 6 O, C 2 H 6 O 2 , BNH 6 , electrolytic MgCl 2 ·21H 2 O solution) is provided, with a discussion of potential technological and geological implications of these experimental findings.
