Abstract

Nanosheets and nanorolls of a metal-organic framework (MOF) with N-donor type neutral bridging ligands were obtained from a layered copper-based MOF by exfoliation treatment in wet process, and were characterized by TEM, SEM, and AFM. The thinnest nanosheet indicates monolayer thickness of the mother MOF.

Functional Porous Coordination Polymers

Susumu Kitagawa, Ryo Kitaura, Shin-ichiro Noro (2004)

The chemistry of the coordination polymers has in recent years advanced extensively, affording various architectures, which are constructed from a variety of molecular building blocks with different interactions between them. The next challenge is the chemical and physical functionalization of these architectures, through the porous properties of the frameworks. This review concentrates on three aspects of coordination polymers: 1). the use of crystal engineering to construct porous frameworks from connectors and linkers ("nanospace engineering"), 2). characterizing and cataloging the porous properties by functions for storage, exchange, separation, etc., and 3). the next generation of porous functions based on dynamic crystal transformations caused by guest molecules or physical stimuli. Our aim is to present the state of the art chemistry and physics of and in the micropores of porous coordination polymers.

Engineering atomic and molecular nanostructures at surfaces.

Johannes V. Barth, Giovanni Costantini, Klaus Kern (2005)

The fabrication methods of the microelectronics industry have been refined to produce ever smaller devices, but will soon reach their fundamental limits. A promising alternative route to even smaller functional systems with nanometre dimensions is the autonomous ordering and assembly of atoms and molecules on atomically well-defined surfaces. This approach combines ease of fabrication with exquisite control over the shape, composition and mesoscale organization of the surface structures formed. Once the mechanisms controlling the self-ordering phenomena are fully understood, the self-assembly and growth processes can be steered to create a wide range of surface nanostructures from metallic, semiconducting and molecular materials.
