Реферат: The temperature sensitivity of paramagnetic chemical shifts in 1H NMR spectra for the [Co(dtpa)]3- complex in 10% gelatin gel (as a model substrate of human or animal tissues) was studied in detail. The maximum temperature sensitivity of the chemical shifts d(δexp)/dT studied in the gelatin gel of the complex was found to be 0.73 ppm/K (which is about 7% higher than in the previously studied D2O solution of the compound). It turned out that the studied complex is characterized by the highest temperature sensitivity of chemical shifts in the NMR spectra among the complexes of paramagnetic d-elements. Moreover, this complex also shows the highest temperature sensitivity of chemical shifts taking into consideration the half-width of the signal itself (|CT|/W= 0.8 K-1). The [Co(dtpa)]3- complex can be considered as a promising compound for the design of temperature-sensitive NMR probes aimed at determining the local temperature in aqueous media and prospective MRI-assisted disease diagnosis.
