Lanthanide complexes of a cyclen derivate with phenylphosphinic pendant arms for possible 1H and 31P MRI temperature sensitive probes.

Abstract

Lanthanide complexes of 1,4,7,10-tetraazocyclodecane-1,4,7,10-tetrakis(methylene(phenylphospinic)acid) (H4L) werw found to give a linear correlations of 1H and 31P NMR chemical shifts to temperature in the physiologically relevant temperature.
