| Popis: | C60 molecules were incorporated into the interlayer of a layered Mg/Al double hydroxide compound, and the physicochemical properties of these spherical molecules arranged in two-dimensional arrays were examined. The precursor used was a double hydroxide with dodecyl sulfate counteranions. C60 molecules were introduced by dissolving the molecules into the interlayer hydrophobic phase. After heating the resultant compound under vacuum to decompose the dodecyl sulfate, C60 molecules were sandwiched in between the double hydroxide layers. The C60-incorporated compounds were characterized with X-ray diffraction, thermal gravimetric analysis, and Raman, UV−vis, and solid state NMR spectroscopies. Among them, the most powerful technique to identify the environment of C60 was solid state 13C NMR. The results of T1 relaxation time and fwhm line width measurement showed that the incorporated C60 molecules did not rotate as freely as in the pure solid form and experienced rather intimate interactions with either the... |
