资源简介：
PCM-16 is a phosphine coordination material comprised
of Dy(III)
and triphenylphosphine oxide, which displays the highest reported
CO2 BET surface area for a Ln(III) coordination polymer
of 1511 m2 g–1. PCM-16 also adsorbs 2.7
wt % H2 and 65.1 wt % O2 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 m2 g–1) via exchange of Me2NH2+ cations
in the pores with smaller NH4+ groups.
