Die Eigenschaften poröser Gerüste lassen sich über mesoskalige Domänen in porösen Koordinationspolymeren (PCPs) einstellen. In ihrer Zuschrift auf S.,4930,ff. beschreiben S. Horike, S. Kitagawa et,al. die Synthese von Kristallen, die zweierlei elastische Schichten enthalten. Über die Zusammensetzung dieser festen PCP-Lösungen können das Gassorptionsverhalten variiert und die Fähigkeit zur Trennung eines CO2/CH4 -Gemischs gegenüber den Stammverbindungen verbessert werden.

Die Trennung von CO2und CH4 in einer Mischung wurde optimiert, indem die Zusammensetzung fester Lösungen aus ineinandergreifenden zweidimensionalen Netzen mit zwei unterschiedlichen Isophthalatliganden variiert wurde (siehe Bild). Die Charakteristika der festen Lösungen hingen vom Verhältnis der Liganden ab, das die Elastizität der Netze und dadurch auch deren Adsorptionseigenschaften beeinflusste. [source]

Deposition of Gold Clusters on Porous Coordination Polymers by Solid Grinding and Their Catalytic Activity in Aerobic Oxidation of Alcohols

Gold clusters were deposited in a narrow size distribution on porous coordination polymers (PCPs) by solid grinding with volatile dimethyl AuIII acetylactonate. The mean diameter could be minimized down to 1.5,nm for Al-containing PCP. Gold clusters on PCPs showed noticeably high catalytic activity in the aerobic oxidation of alcohols. Product selectivity was tunable by the selection of PCP supports in benzyl alcohol oxidation. [source]

Porous Porphyrin Nanoarchitectures on Surfaces

EUROPEAN JOURNAL OF INORGANIC CHEMISTRY, Issue 24 2010

Abstract Controlling the size and the growth direction of porous hybrid objects , metal,organic frameworks (MOFs) or porous coordination polymers (PCPs) , at the nanoscale is a critical issue for enabling their use in a number of potential applications that have arisen from the current remarkable activity in studying such porous materials. This microreview describes the recent progress in the design, growth, and characterization of multidimensional nanoarchitectures by employing porphyrin-based components. The versatility of the sequential bottom-up fabrication process, which uses multitopic molecular building units assembled by appropriately chosen linkers, is suitable to be extended to the formation of a rich variety of nanostructures endowed with pores on surfaces.
