copper oxide nanostructures have been successfully synthesized via one-step solid-state thermolysis of two metal-organic frameworks, [cu3(btc)2] (1) and [cu(tpa).(dmf)] (2), (btc = benzene-1,3,5-tricarboxylate, tpa = therephtalic acid = 1,4-benzendicarboxylic acid and dmf = dimethyl formamide) under air atmosphere at 400,  500, and 600°c. it has also been found that the reaction temperature pla...

metal-organic frameworks (mofs) represent a new class of highly porous materials. on this regard,  two nano porous metal-organic frameworks of [zn2(1,4-bdc)2(h2o)2∙(dmf)2]n (1) and [zn2(1,4-bdc)2(dabco)]·4dmf·1⁄2h2o (2), (1,4-bdc = benzene-1,4-dicarboxylate, dabco = 1,4-diazabicyclo[2.2.2]octane and dmf = n,n-dimethylformamide) were synthesized and characterized. they were used for preparation ...
