Реферат:
By 1 Н dynamic NMR method the conformational reorientation of the 18-crown-6 ether molecules in [(Ce(ptfa)3 )2 (18- crown-6)] complexes has been experimentally studied in the CDCl3 solution. The results of the present work demonstrate that there is a conformational dynamic processes in [(Ce(ptfa)3 )2 (18-crown-6)] complex (with the activation free energy ∆G‡ (320K) = 49 ± 4 kJ/mol ). It is conditioned by conformational reorientation of 18-crown-6 molecule. These complexes are promising to be subnanoscale NMR spectroscopic probes to determine the temperature in nonaqueous media.
