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.
