Inelastic electron transport in C70 fullerene

open access: yes, 2016
The effect of inelastic electron-phonon interactions on thermoelectric and electron transport properties of the C70 molecule has been studied. The results show that thermopower sign is positive for negative energies; while for positive energies it ...

Neat C60:C70 buckminsterfullerene mixtures enhance polymer solar cell performance

open access: yes, 2014
We demonstrate that bulk-heterojunction blends based on neat, unsubstituted buckminsterfullerenes (C60, C70) and a thiophene–quinoxaline copolymer (TQ1) can be readily processed from solution.

Designing Tailored Molecular Cavities Using Calix[5]arenes as Building Blocks

open access: yesThe Chemical Record, Volume 26, Issue 6, June 2026.
This account focuses on the shape and dimensions of cavities formed by precisely designed molecular frameworks. It highlights our efforts to construct synthetically tailored cavities based on calix[5]arenes. This study examines the shapes and dimensions of cavities defined by well‐designed molecular structures.

Theoretical Raman spectroscopy study of finite and infinite fullerene chains inside single-walled carbon nitride nanotubes

open access: yesMaterials and Devices, 2019
We investigated the hybrid system between Nitrogen doped Single Wall Carbon Nanotubes (N-SWCNT) and fullerene (C60  C70) molecules. The structure of the encapsulated fullerenes inside N-SWCNTs is derived from minimum energy calculation using a ...

Studies on Electronic Structures and Spectra of Fullerenes Doped with Nitrogen and Boron(氮杂及硼杂碳笼的电子结构和光谱研究)

open access: yesZhejiang Daxue xuebao. Lixue ban, 1999
用INDO方法研究了氮杂与硼杂碳笼CnX(n=59,69;X=N+,B-)的电子结构和光谱,表明CnX与C60,C70相比将发生结构畸变,氮杂碳笼比硼杂碳笼稳定,C70中靠近极附近的两种C原子易被杂原子置换.本文在对电子跃迁进行理论指认的同时,讨论了光谱红移的原因.
