Porous coordination polymers PCPs

Fig. 6 Porous coordination polymer (PCP) developed by Kitagawa and coworkers. The pores, which extend throughout the array, can be filled by C02 molecules (grey and red), allowing these materials to employ their high internal surface area as gas adsorbents [13]. Reprinted with permission...

Recently, porous coordination polymers (PCPs), prepared using self-assembling processes from metal ions and organic ligands, have attracted much attention because of their wide applications in gas storage, molecular recognition and separation, and catalysis, utilizing their crystalline, robust - yet flexible - porous... 

The simplicity of synthesis with no necessity for the use of organic templates and other structure-directing agents, and for high-temperature calcinations to remove the template makes MOFs competitive in comparison with zeolites. The principles of the modular chemistry and methodology of synthesis of MOFs and, in general, porous coordination polymers (PCPs) are presented in a few very good recent reviews [23-25]. The synthesis and properties of the new JUC family of MOFs (JUC is the abbreviation of Jilin University China) is the focus of the review [26]. 

Gold could be deposited on porous coordination polymers (PCPs) as clusters and nanoparticles smaller than 5 mn by grinding dimethyl Au(III) acetylacetonate with PCPs. In particular, on Al-containing PCP, the mean diameter of Au was minimized to 1.6 mu. These tiny Au clusters exhibit markedly high catalytic activity and selectivity in A-alkylation of amine with alcohol under N2. 

Porous coordination polymers (PCPs), having highly ordered nanometer-sized porous structures, have recently been attracting interests as supports for metal clusters [3]. However, it was difficult to deposit Au as clusters on or in PCPs by conventional chentical vapor deposition (CVD). In this work, we demonstrated the direct deposition of Au as clusters onto PCPs by a solid grinding method and investigated their catalytic performance for one-pot A/-aIkylation of amine with alcohol. 

The term MOF was coined by Professor Omar Yaghi of the University of California, Los Angeles. These types of supramolecular materials have also been called coordination networks or porous coordination polymers (PCPs). The use of the term coordination refers to the type of bond between the organic molecules and the metal ions, which are often referred to as coordination bonds. Materials that ht the description of MOFs were described prior to Professor Yaghi s coining of that particular term, but since then, the use of the term MOF has become the dominant acronym for these materials.
