Metal–organic frameworks for luminescence thermometry

Metal-organic frameworks (MOFs) hold great promise for developing various types of luminescent sensors due to their remarkable structural diversity and tunable luminescence properties. In the last few years, utilizing luminescent MOFs to explore temperature sensing has gained intense attention. In this feature article, after the general description of luminescence thermometry, we have summarized the recent progress made in luminescent MOF thermometers, with particular emphasis on the dual-emitting MOFs that effectively illustrate the self-referencing temperature measurement based on the intensity ratios of two separate transitions.
