Resumen:
PCM-16 is a phosphine coordination material comprised of Dy(III) and triphenylphosphine oxide, which displays the highest reported CO 2 BET surface area for a Ln(III) coordination polymer of 1511 m 2 g -1. PCM-16 also adsorbs 2.7 wt % H 2 and 65.1 wt % O 2 at 77 K and 0.97 bar. The adsorption-desorption behavior of a series of organic vapors has been studied in PCM-16 to probe the nature of certain host-guest interactions in the pores. Aromatic and polar guest species showed high uptakes and marked adsorption/desorption hysteresis, while aliphatic vapors were less easily adsorbed. The surface area of PCM-16 could be increased significantly (to 1814 m 2 g -1) via exchange of Me 2NH 2 + cations in the pores with smaller NH 4 + groups. © 2012 American Chemical Society.
