| Abstract: | A molecular complex of fullerene C60 with triptycene, TPC·C60 is obtained. The complex has a three-dimensional packing of C60 molecules. According to the IR spectra, the freezing of free rotation of C60 molecules in the complex is maintained up to 360 K. The XP-spectra of TPC·C60 show the suppression of π–π* transitions of TPC phenylene rings. The separation of C60 molecules by TPC ones in TPC·C60 results in low intensity of the C60 transitions in the 420–500 nm range in an optical spectrum. This absorption is assumed as that attributed to intermolecular transitions between adjacent C60 molecules. |
