Modulated self-assembly of three flexible Cr(iii) PCPs for SO(2) adsorption and detection

Modulated self-assembly protocols are used to develop facile, HF-free syntheses of the archetypal flexible PCP, MIL-53(Cr), and novel isoreticular analogues MIL-53(Cr)-Br and MIL-53(Cr)-NO(2). All three PCPs show good SO(2) uptake (298 K, 1 bar) and high chemical stabilities against dry and wet SO(2...

Sumario:Modulated self-assembly protocols are used to develop facile, HF-free syntheses of the archetypal flexible PCP, MIL-53(Cr), and novel isoreticular analogues MIL-53(Cr)-Br and MIL-53(Cr)-NO(2). All three PCPs show good SO(2) uptake (298 K, 1 bar) and high chemical stabilities against dry and wet SO(2). Solid-state photoluminescence spectroscopy indicates all three PCPs exhibit turn-off sensing of SO(2), in particular MIL-53(Cr)-Br, which shows a 2.7-fold decrease in emission on exposure to SO(2) at room temperature, indicating potential sensing applications.
