Obtaining an understanding, at the atomic level, of the interaction of nanomaterials with biological systems has recently become an issue of great research interest. Here we report on the molecular dynamics study of the translocation of fullerene C60 and its derivative C60(OH)20 across a model cell membrane (dipalmitoylphosphatidylcholine or DPPC bilayer). The simulation results indicate that, ...

In this study, four kinds of structures—[6,6]-phenyl-C61-butyric acid methyl ester (PCBM), PCBM/fullerene (C60), C60/bathocuproine (BCP), and PCBM/C60/BCP—were used as electron transport layers, and the structure, and optical and electronic behaviors of MAPbBr3 perovskite layers after annealing treatments were observed. The experimental results indicate that PCBM/C60 bi-layer structure is accep...

We have used dielectric spectroscopy to measure the frequency and temperature dependence of the lowfrequency ~0.5 mHz–100 kHz! complex dielectric function «(v) of thin C60 films. A small charge transfer occurs between the C60 and O2 molecules which occupy interstitial spaces of solid C60 exposed to oxygen ~or ambient air!. Due to the large size of the C60 molecules, this small charge transfer c...

Learning to engineer self-assembly would enable the precise organization of molecules by design to create matter with tailored properties. Here we demonstrate that proteins can direct the self-assembly of buckminsterfullerene (C60) into ordered superstructures. A previously engineered tetrameric helical bundle binds C60 in solution, rendering it water soluble. Two tetramers associate with one C...

The first system containing a luminescent Ir(m) cyclometallated species and a functionalized C60 unit has been prepared; triplet-triplet energy transfer from the Ir-based MLCT state to the C60 triplet state occurs, leading to phosphorescence (lifetime, 4.8 ms) of the derivatized-C60 at 77 K.

Molecular heterojunctions, such as the one based on copper phthalocyanine (CuPc) and carbon fullerene (C60) molecules, are commonly employed in organic photovoltaic cells as electron donor–acceptor pairs. We have investigated the different atomic structures and electronic and optical properties of the C60/CuPc heterojunction through first-principles calculations based on density functional theo...

Solution-processed organic field effect transistors (OFETs), which are amenable to facile large-area processing methods, have generated significant interest as key elements for use in all-organic electronic applications aimed at realizing low-cost, lightweight, and flexible devices. The low performance levels of n-type solution-processed bottom-contact OFETs unfortunately continue to pose a bar...

The geometric and electronic structures of a monolayer of C60 on a h-BN monolayer-covered Ni 111 surface are studied by first-principles calculations. The interaction between ions and electrons is described by the projector-augmented plane-wave method. The most stable structure of the h-BN/Ni 111 surface is found to be N on the top and B on the fcc site of Ni 111 . Upon adsorption, the structur...

A new functionalized [60]fullerene-glycidyl azide polymer (C60-GAP) was synthesized for the first time using a modified Bingel reaction of [60]fullerene (C60) and bromomalonic acid glycidyl azide polymer ester (BM-GAP). The product was characterized by Fourier transform infrared (FTIR), ultraviolet-visible (UV-Vis), and nuclear magnetic resonance spectroscopy (NMR) analyses. Results confirmed t...

The change of conductance of single-molecule junction in response to various external stimuli is the fundamental mechanism for the single-molecule electronic devices with multiple functionalities. We propose the concept that the conductance of molecular systems can be tuned from inside. The conductance is varied in C60 with encapsulated H2O, H2O@C60. The transport properties of the H2O@C60-base...
