Sažetak
The spectral behavior of the spin probe TEMPO in the bulk cyclohexane (CHX) and its confined states in a series of silica gels (SG) using ESR is reported. The spectral parameter Azz’ and the characteristic ESR temperature T(50G) of slow to fast regime transition of TEMPO change dramatically in the virgin SG-SIL‘s compared to the bulk CHX sligtly depending on the pore size. These observations result from the interrelation between the mutual interaction of the TEMPO with the SG‘s and the altered phase behavior of the CHX from DSC. This is supported by the modified (silanized) SG matrices.
