WebNov 6, 2014 · Phosphine metal–organic frameworks (P-MOFs) are crystalline porous coordination polymers that contain phosphorus functional groups within their pores. We present the use of X-ray absorption spectroscopy (XAS) at the P K-edge to determine the phosphine to phosphine oxide ratio in two P-MOFs with MIL-101 topology. WebPhosphine sulfides, known as a pentavalent class of organophosphines, have attracted relatively less attention compared to wide applications of trivalent organophosphines. 1 Over the decades, much attention has been paid to specially designed trivalent organophosphines for selective transition-metal catalysis. 2 Although those organophosphine …
