Abstract
- 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 <subscript>2</subscript> . All three PCPs show good SO <subscript>2</subscript> uptake (298 K, 1 bar) and high chemical stabilities against dry and wet SO <subscript>2</subscript> . Solid-state photoluminescence spectroscopy indicates all three PCPs exhibit turn-off sensing of SO <subscript>2</subscript> , in particular MIL-53(Cr)-Br, which shows a 2.7-fold decrease in emission on exposure to SO <subscript>2</subscript> at room temperature, indicating potential sensing applications.
