AI Article Synopsis
- Researchers developed easy, HF-free methods to create flexible porous coordination polymers (PCPs) like MIL-53(Cr) and its new variants MIL-53(Cr)-Br and MIL-53(Cr)-NO.
- All three PCPs effectively absorb SO at room temperature and maintain their chemical stability in both dry and wet conditions.
- MIL-53(Cr)-Br displayed significant changes in light emission when exposed to SO, suggesting its potential use in sensing technologies.
Article 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. All three PCPs show good SO uptake (298 K, 1 bar) and high chemical stabilities against dry and wet SO. Solid-state photoluminescence spectroscopy indicates all three PCPs exhibit turn-off sensing of SO, in particular MIL-53(Cr)-Br, which shows a 2.7-fold decrease in emission on exposure to SO at room temperature, indicating potential sensing applications.
