Abstract

A strategy to achieve a ratiometric thermometer by encapsulating luminescent perylene dye into the pores of a europium metal–organic framework (MOF) is developed. The resulting MOF⊃dye thermometer exhibits highly temperature-dependent luminescence intensity ratio over the physiological temperature range, with a maximum sensiti­vity of 1.28% °C−1 at 20 °C.
