“…In the field of organic solar cells and organic field effect transistors, they are applied because of their n-type semiconductor character accompanied by a relatively high mobility [2,3]. They are also utilized as building units in organic frameworks, e.g., for low-k materials [4,5], and they are investigated as charge trapping centers in organic and inorganic matrices for memory devices [6,7]. In addition, fluorinated fullerenes are seen as candidates for cathode materials of high energy density batteries [8].…”

“…In this paper, we have carried out a combined Near-Edge X-ray Absorption Fine Structure Spectroscopy (NEXAFS) and X-ray/UV Photoemission Spectroscopy (XPS/UPS) study on C 60 , [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) and fullerenols in order to understand the chemical bonding and the electronic structures of the materials. These techniques are powerful for the monitoring of unoccupied and occupied states.…”

We have studied thin films of C 60 , [6,6]-phenyl-C61-butyric acid methyl ester, and fullerenol by Near-Edge X-ray Absorption Fine Structure Spectroscopy at the C1s edge. The advantage of this technique is the sensitivity to unoccupied π states within the sp 2 chemical bond structure. In particular, we focus on the relative intensity of the C1s→π*(p-p) transitions. Upon adding functional groups to the C 60 molecular frame, the intensity of these bands is reduced or almost vanished accompanied by increasing C1s→π*(s-p) transitions. This finding is confirmed by Xray photoemission data in the valence band region where the peaks according to the occupied π states disappeared particularly in the fullerenol films. These data in combination with the quantitative analysis of the C1s core level data suggest that C=C double bonds are broken when binding two OH-groups correlated to a change of the carbon bonding state from sp 2 to sp 3 .

The initial adsorption of C60 molecules on an Al nanocluster array template, an Si(111)-7×7 surface with an Al nanocluster array, was observed at various temperatures using a variable temperature scanning tunneling microscope (STM). STM images showed that C60 molecules stay above the dimer lines near the corner hole, with one of the 6-6 bonds facing toward the adsorbing surface and forming chemical bonds with two neighboring corner Si adatoms. The strong interaction immobilized C60 molecules on the adsorbing template.

“…It is stabilized by electron resonance and can tolerate extreme temperature and pressure conditions (Chuvilin et al, 2010). Fullerenes have attracted extensive attention in various fields including optoelectronics (Tutt and Kost, 1992), information technology (Senftleben et al, 2009), biomedical (Q. Liu et al, 2014;Markovic and Trajkovic, 2008;Stoilova et al, 2007), etc.…”

A Theoretical Perspective on Strategies for Modeling High Performance Nonlinear Optical Materials

Nonlinear optical (NLO) materials have spanned a large area of science and technology owning to their potential applications in optoelectronics. The invention of the first Ruby laser has sparked a fresh interest in the area of nonlinear optics. The computational designing and experimental synthesis of organic and inorganic NLO materials with higher order nonlinearities come into vogue in the field of materials science. To date, several strategies including metal ligand framework, push pull mechanism, diradical character, and so on have been devised to enhance the NLO response of materials. In addition, introduction of diffuse excess electrons is an efficient approach to design noncentrosymmetric materials for nonlinear optics. The current review highlights a systematic array of different computational studies (covering the last decade of intensive research work) for the theoretical designing of NLO materials. In the present review, theoretical designing from the simplest NLO material to the complex alkali, alkaline earth, transition, and superalkali doped nanomaterials is summarized. The emergence of excess electrons strategy has played a pivotal role in enhancing the NLO properties especially hyperpolarizabilities. We expect that this review will provide a better understanding of the NLO responses of nanoclusters, paving the way for the advancement of hi-tech NLO materials to meet the real challenges in optoelectronics.
