Ring Opening Reactions of Fullerenes: Designed Approaches to Endohedral Metal Complexes

Yves Rubin

Topics in Current Chemistry > Fullerenes and Related Structures > 67-91

Endohedral complexes of fullerenes are some of the most attractive targets of research in fullerene chemistry and physics. An overview of the field is provided with a focus on endohedral complexes incorporating lanthanide metals, noble gases, and atomic nitrogen. Although the present approaches have been successful in providing the first members of this class of fullerenes, their preparation is still...

Regioselective Cage Opening of La₂@D₂(10611)‐C₇₂ with 5,6‐Diphenyl‐3‐(2‐pyridyl)‐1,2,4‐triazine

Michio Yamada, Yasuhiro Muto, Hiroki Kurihara, Zdenek Slanina, więcej

Angewandte Chemie > 127 > 7 > 2260 - 2263

The thermal reaction of the endohedral metallofullerene La₂@D₂(10611)‐C₇₂, which contains two pentalene units at opposite ends of the cage, with 5,6‐diphenyl‐3‐(2‐pyridyl)‐1,2,4‐triazine proceeded selectively to afford only two bisfulleroid isomers. The molecular structure of one isomer was determined using single‐crystal X‐ray crystallography. The results suggest that the [4+2] cycloaddition was...

Understanding Local and Macroscopic Electron Mobilities in the Fullerene Network of Conjugated Polymer‐based Solar Cells: Time‐Resolved Microwave Conductivity and Theory

Jordan C. Aguirre, Christopher Arntsen, Samuel Hernandez, Rachel Huber, więcej

Advanced Functional Materials > 24 > 6 > 784 - 792

The efficiency of bulk heterojunction (BHJ) organic photovoltaics is sensitive to the morphology of the fullerene network that transports electrons through the device. This sensitivity makes it difficult to distinguish the contrasting roles of local electron mobility (how easily electrons can transfer between neighboring fullerene molecules) and macroscopic electron mobility (how well‐connected is...

Pentaarylazafullerene und ihre Triaryldihydro‐ und Tetraarylmonohydro‐Zwischenstufen

Regina Neubauer, Frank W. Heinemann, Frank Hampel, Yves Rubin, więcej

Angewandte Chemie > 124 > 47 > 11892 - 11896

Synthese von Heterofulleren‐Pentaaddukten: Die Titelverbindungen wurden nach säurekatalysierten Reaktionen einer C₅₉N‐Vorstufe mit elektronenreichen Arenen isoliert. Röntgenstrukturanalysen zweier Derivate zeigen charakteristische Packungsmotive. Das Triaryldihydro‐Derivat ist das erste Multihydroheterofulleren; es weist im Kristall eine pseudo‐gestapelte Anordnung auf (C violett/gelb, N blau, O rot,...

Pentaarylazafullerenes and their Triaryldihydro and Tetraarylmonohydro Precursors

Regina Neubauer, Frank W. Heinemann, Frank Hampel, Yves Rubin, więcej

Angewandte Chemie International Edition > 51 > 47 > 11722 - 11726

Give me five! The title compounds were isolated from the acid‐catalyzed reaction of a C₅₉N precursor with electron‐rich aromatic compounds. Single‐crystal X‐ray diffraction on two compounds reveals characteristic packing motifs; the triaryldihydro derivative has a pseudo‐stacked arrangement (C violet/yellow, N blue, O red, H white).

Crystal‐Packing Trends for a Series of 6,9,12,15,18‐Pentaaryl‐1‐hydro[60]fullerenes

Robert D. Kennedy, Merissa Halim, Saeed I. Khan, Benjamin J. Schwartz, więcej

Chemistry – A European Journal > 18 > 24 > 7418 - 7433

The relationship between the size of the substituents of aryl groups in a series of fifteen 6,9,12,15,18‐pentaaryl‐1‐hydro[60]fullerenes and the solid‐state structures and packing motifs of these compounds has been analyzed. Pentaarylfullerenes have a characteristic “badminton shuttlecock” shape that causes several derivatives to crystallize into columnar stacks. However, many pentaarylfullerenes...
