4. Crystallographic evidence and spin activation for the Russian-doll-type metallofullerene Sc4C2@C80.

Author

Subjects
ELECTRON paramagnetic resonance spectroscopy, RADICAL cations, OXIDATION states
Abstract

We report unambiguous crystallographic evidence for the Russian-doll-type metallofullerene Sc4C2@Ih-C80. 45Sc NMR further demonstrates the tetrahedron arrangement of the Sc4C2 cluster. Moreover, the electrochemical test reveals the stable oxidation state of Sc4C2@C80. Hence, the Sc4C2@C80 cation radical was studied by electron spin resonance spectroscopy. These results provide better understanding for the previously less-explored Sc4C2@C80. [ABSTRACT FROM AUTHOR]

10. A temperature-responsive C2 wagging vibration in Sc2C2@Cs-C82.

Author

Wu, Bo, Wang, Taishan, Zhang, Zhuxia, Jiang, Li, and Wang, Chunru

Subjects
*TEMPERATURE effect, *MOLECULAR vibration, *RAMAN spectra, *MICROENCAPSULATION, *ELECTRON microscopy, *DENSITY functional theory
Abstract

The Raman spectra reveal molecular vibration information. Here we report a special temperature-dependent C2 wagging vibration at 225 cm−1 in Sc2C2@Cs-C82 by Raman spectroscopy and quantum-chemical calculations, which corresponds to the internal cluster motion in C82. This finding is of great importance in understanding the internal dynamics of metallofullerenes. [ABSTRACT FROM AUTHOR]

12. An effective retro-cycloaddition of M3N@C80 (M = Sc, Lu, Ho) metallofulleropyrrolidines.

Abstract

Sc3N@C80 fulleropyrrolidines are typical metallofullerene derivatives which were generated by the reaction of Sc3N@C80 with N-trityloxazolidinone. Here we report an effective retro-reaction of Sc3N@C80 fulleropyrrolidine by using 3-chloroperoxybenzoic acid to give pristine Sc3N@C80 in a high yield. This technique is expected to be used for separating metallofullerenes (M3N@C80) from hollow fullerenes without HPLC. [ABSTRACT FROM AUTHOR]

13. Indan-C60: from a crystalline molecule to photovoltaic application.

Author

Wang, Taishan, Liao, Xiaxia, Wang, Jizheng, Wang, Chunru, Chan, Mei-Yee, and Yam, Vivian Wing-Wah

Subjects
*INDAN, *PHOTOVOLTAIC power generation, *CRYSTALS, *NANOSTRUCTURED materials, *ELECTRIC power conversion
Abstract

Crystalline Indan-C60 and its photovoltaic application were studied. Microsheets and aloe-like micro-nano superstructures can be assembled from Indan-C60. Indan-PC61BM derived from Indan-C60 was further investigated as an acceptor for OPV devices, which shows a higher Voc, FF, and PCE than those obtained using PC61BM. [ABSTRACT FROM AUTHOR]
