Abstract:
Macromolecular recognition systems are difficult to construct because extremely high recognition ability is required to form a stable host-guest complex toward macromolecules. Herein, we report a novel host-guest recognition motif based on C-propylpyrogallol[4]arene (PgC) and a commercially available polymer, polyethylene glycol (PEG). The results show that PgC can selectively entrap PEG with higher molecular weights to form bilayered host-guest complex structures. Interestingly, this host-guest recognition is strong enough that PgC is able to adsorb PEG from an aqueous solution efficiently.

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.
