A Three-dimensional MOF Assembled by Metal-organic Tapes Comprising of Copper(II)Tetranuclear Clusters and 5-Sulfoisophthalates

摘要

Growing efforts to construct new MOFs(metal-organic frameworks)have been focused at developing functional materials exhibiting applicable catalytic,gas storage and separation,magnetic,and sensing properties.Currently,one of the most challenging goals in the field of MOF chemistry is to build the frameworks by design in order to endow them those properties or improved functions.Several research groups have developed and demonstrated rational design sterategies toward desired framework structures and in turn better functional materials.However,as there are many framework structures that do not follow nature's default network types,many examples for the unprecedented structures need to be explored and classfied to figure out their assembling patterns or rules as demonstrated by the cases of 1D infinite chains.Here we present a rare example that 1D metal-organic frameworks containing an unusual copper tetranuclear inorganic building block are assemlbed to form a 3D framework.Before our work,two MOFs sharing similar structural features as our case were reported.However,our preparation method is simpler and milder than the reported ones,and in addition,the crystal strcuture is slightly different from those due to the changes in the additional coordinating ligands.
