Tunable hydrophobicity: Efficient air filters for the protection against chemical warfare agents might be achieved by surface functionalization of the pores in robust metal–organicframeworks (MOFs) with fluoroalkyl residues and the precise control of their pore size (see picture). These MOFs captureharmfulvolatileorganiccompounds even under extremely moist conditions (80 % relative humidity).

oxygen from air remains a significant challenge. Here, we show that chemically reduced metal-organicframework materials of the type AxFe2(bdp)3 (A = Na+, K+; bdp2- = 1,4-benzenedipyrazolate; 0 < x ≤ 2), which feature coordinatively saturated iron centers, are capable of strong and selective adsorption of O2 over N2 at ambient (25 °C) or even elevated (200 °C) temperature.
