Abstract
Disclosed are air-stable small-molecule adsorbents trimeric [Cu—Br]3 and [Cu—H]3 that undergo a reversible solid-state molecular rearrangements to [Cu—Br.(alkene)]2 and [Cu—H.(alkene)]2 dimers. The reversible solid-state rearrangement allows one to break adsorbent design trade-offs and achieve low heat of adsorption while retaining high selectivity and uptake.
Claims21
A composition comprising an alkene and a compound having Formula I:
- wherein each X is, independent of the other, chosen from H and Br;
- and each Y is, independent of the other, chose from CF3, C2F5, C3F7, C4F8, F, Cl, Br, and I.
A complex having Formula II:
- wherein each X is, independent of the other, chosen from H and Br;
- and each Y is, independent of the other, chosen from CF3, C2F5, C3F7, C4F8, F, Cl, Br, and I.
A method of separating an alkene from a mixture comprising the alkene and an alkane, comprising:
- contacting the mixture with a compound having Formula I:
- to form a complex having Formula II
- wherein each X is, independent of the other, chosen from H and Br;
- and each Y is, independent of the other, chosen from CF3, C2F5, C3F7, C4F8, F, Cl, Br, and I.
