چکیده
2 3 3 3 2 Na[BH(C H N ) ]·solvent (solvent = H O, DMF, IPA) crystallize as a porous framework with the distorted primitive cubic (pcu) topology. Solvent molecules occupy the framework pores. The solvent of crystallization can be removed by heating. Isothermal thermogravimetric analysis shows that solvent loss is consistent with a 1-D diffusion mechanism. Variable temperature powder X-ray diffraction (PXRD) data show some loss of crystallinity upon desolvation, indicating some framework decomposition. These materials adsorb water from the atmosphere. The structures of

Redox-Active Metal-Organic Nanostructure Polymers and Their Remarkable Electrochemical Behavior
A number of redox-active coordination polymers (CPs) or metal- organic frameworks (MOFs) have been successfully synthesized using transition metals and bridging ligands. This article aims to deal with gathering the aforementioned disperse issues regarding the electroactive CPs. It also goes towards illustrating the effects of various factors on the electrochemical behavior of CPs including...
متن کاملInfluence of amine group on the adsorptive removal of basic dyes from water using two nanoporous isoreticular Zn(II)-based metal organic frameworks
Dyes are the most abundant hazardous components existing in the environment because of their extensive use in industries. So, in the present study, two isoreticular Zn(II)-MOFs, TMU-16 and TMU-16-NH2, were used for the adsorptive removal of harmful cationic dyes from aquatic medium. In order ...

متن کاملMetal-organic framework materials as nano photocatalyst
Photocatalytic degradation of toxic organic compound in water, soil and air by semiconductor catalysts such as TiO2 and ZnO have received much attention over the last two decades. However, the low quantum yield, easy agglomeration and difficult post-separation of these inorganic catalysts limit their application for large-scale applications. Metal-organic frameworks (MOFs) are the latest class ...
