What Does MOF stand for
metal-organic framework
Define a MOF
crystalline compound consisting of metal ions or clusters coordinated to often ridged organic molecules to form 1, 2, or 3 d structures that can be porous
What are hybrid frameworks
another name for MOFs
what are coordination polymers
another name for MOFs
What is MOF-5 made of
ZnO4 tetrahedra joined by benzene dicarboxylate linkers
What is the Structure of MOF-5
extended 3D cubic framework with interconnected pores of 8 A aperture width and 12 A pore diameter
What is the topology of MOF-5
cubic net
Are MOFS or zeolites more flexible
MOFs
Are MOFs or zeolites more chemically diverse
MOFs
Are you able to synthesize MOFs or zeolites at room temp
MOFs
Do you need to calcine MOFs to remove the template
No
Do MOFs are zeolites have a broader range of textual properties (pore size, surface area, pore volume)
MOFs
Do MOFs are zeolites have higher surface area
MOFs
What does ZIFs stand for
Zeolite Imidazolate Frameworks
How do ZIFs compare to zeolites (SiO4, AlO4)
Transition metal atoms (Zn, Co) replace T atoms and imidazolates replace bridging oxygen atoms

aperture size: 0.34 nm pore size: 1.16 nm
What are some examples of CoN4 ZIFs aperture and pore size
Aperture size: 0.34 nm, pore size: 1.04 nm Aperture size: 0.34 nm, pore size: 1.16 nm
What is an example of ZnN4 ZIF aperture and pore size
Aperture size: 0.29 nm, pore size: 0.36 nm
What are the important properties of ZIFS
high surface area (100-4500 m^2/g) thermal/chemical stability microporous crystalline structures (functionality) polar walls (uncoordinated N atoms)
What does BioMOFs stand for
Bio-metal-organic frameworks
What is the relationship between MOFs and BioMOFS
BioMOFS are MOFS with metal ions coordinate with at least one biomolecule serving as organic linker forming a crystalline porous framework
What type of biomolecules make up BioMOFs
aminoacids, peptides, proteins, saccharides, and nucleobases
What is BioMOF-1 made of
Cages consist of 8 Zn2+ cations with 4 adeninate liners columns composed of octahedral cages columns interconnected with biphenyldicarboxylate linkers
What is the structure of BioMOF-1
