Catching up on papers and emails from over Christmas and I came across this: http://dx.doi.org/10.1021/acs.cgd.7b00808 talking about the definition of a MOF, and it makes some really good arguments on how to improve it. #RealTimeChem #MOF
1) I really like the definition proposed there, though I'm surprised 2D structures are allowed: "a class of Coordination Polymers comprising organic linkers wherein metal-ligand interaction/bonding leads to 2D or 3D crystalline network structure"
5) I'd like to hear more about amorphous coordination polymers. As a CP chemist I've been using a working definition that they must be crystalline since they need short and long range order.
@Canageek am I missing a part 4?
@DialMforMara No, on twitter I put the definition as part 4, as I forgot it at the start and forgot to update the numbering when I fixed that here.
2) I feel vindicated that porosity isn't a part of the definition. It is hard to test, changes from gas to gas, and isn't implicit in any of the words metal, organic, or framework.
3) I think he could have made the organic section more clear and shorter if he considered the organic definition I was taught: "Has a carbon-hydrogen backbone" as that limits several of his edge cases.
