Аннотация

Electron paramagnetic resonance spectroscopy in the framework of the spin probe technique is applied to estimate the effect of the structure of molecules as an example of nitroxyl radicals on their localization in aqueous solutions of thermoresponsive poly-N-isopropylacrylamide during the coil-to-globule phase transition. It is shown that the small hydrophobic 4-hydroxybenzoate-TEMPO probe is almost completely localized in the globule formed during the phase transition, while the large probe containing a long alkyl tail (methyl 5-doxyl stearate) does not enter the compact polymer globule.
