METAL–ORGANIC FRAMEWORK

Article : 76,194 Patent : 2,487

DEFINITIONS

Metal-organic frameworks (MOFs) are constructed by joining metal-containing units with organic linkers, using strong bonds (reticular synthesis) to create open crystalline frameworks with permanent porosity.

Reference : H. Furukawa et al., Science 341 (2013) 1230444

MOFs are a new class of emerging crystalline porous solids with three-dimensional (3D) networks that consist of coordination bonds between transition-metal cations and multidentate organic linkers.

h-Index of nanotechnology publications

This field displays the h-index count and is based on a list of publications ranked in descending order by the Times Cited count. The h-index is the number of the item/publication in the h rank of the mentioned ranking that has at least "h" citations. For example, an h-index of 20 means 20 items have 20 citations or more. This metric is useful because it discounts the disproportionate weight of highly cited papers or papers that have not yet been cited.
