Coordination polymers Two-dimensional polymer

synthetic scheme metal organic framework (mof) using hexahydroxytriphenylene (hhtp) , cu(ii) metal.


metal organic frameworks

self-assembly can observed in presence of organic ligands , various metals centers through coordinative bonds or supramolecular interactions. molecular self- assembly involves association many weak, reversible interactions obtain final structure represents thermodynamic minimum. class of coordination polymers, known metal-organic frameworks (mofs), metal-ligand compounds extend infinitely one, 2 or 3 dimensions.

mof synthesis

availability of modular metal centers , organic building blocks generate wide diversity in synthetic versatility. applications range industrial use chemiresistive sensors. ordered structure of frame largely determined coordination geometry of metal , directionality of functional groups upon organic linker. consequently, mofs contain highly defined pore dimensions when compared conventional amorphous nanoporous materials , polymers. reticular synthesis of mofs term has been coined describe bottom-up method of assembling cautiously designed rigid molecular building blocks prearranged structures held strong chemical bonds. synthesis of two-dimensional mofs begins knowledge of target blueprint or network, followed identification of required building blocks assembly.

by interchanging metal centers , organic ligands, 1 can fine-tune electronic , magnetic properties observed in mofs. there have been recent efforts synthesize conductive mofs using triyphenylene linkers. additionally, mofs have been utilized reversible chemiresistive sensors.
