Two fluorinated thulium complexes as molecular temperature sensors in MR applications†
Abstract
19F-based magnetic resonance is a powerful tool to overcome several difficulties of standard 1H MR. We present the syntheses and characterization (including cell viability and stability tests) of two Tm3+ complexes. Both complexes allow the detection of temperature (ΔCT = −0.2319 ppm K−1 and −0.2122 ppm K−1) without a reference compound.
