Acetylene, an important petrochemical raw material, is very difficult to store safely under compression because of its highly explosive nature.

Crystal engineering of metal-organic frameworks (MOFs) has allowed the construction complex structures at atomic precision, but yet to reach same level sophistication as organic synthesis.
