The present work describes a supramolecular strategy for the molecular recognition and selective separation of extended PAHs and NGs from isomeric mixtures. This approach consists of a biphasic protocol featuring the selective shuttling of a targeted NG isomer from the organic to the aqueous phase, driven by host-guest interactions with a tetragonal prismatic metal-organic cage (MOC) present in the aqueous layer, while the cage remains permanently confined to the aqueous phase, operating as a static supramolecular receptor throughout the separation process.

Stability of Conjugated Dienes
A comparison of the enthalpies of hydrogenation of dienes reveals that conjugated dienes release less heat on hydrogenation, rendering them more stable than their nonconjugated analogs.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
