“…[19,21] From the outset, thin films of fullerenes have been the focal point of research. Upon reduction, fullerenes show novel superconducting, [22] magnetic, [23,24] nonlinear optical, [25] and photochemical properties. [26] Therefore, the electrochemical behavior of thin films of C 60 has been extensively studied, [27±29] and found to be very different from that of the dissolved species.…”

Solution-cast films of the major isomer of Dy@C(82) (Dy@C(82)(I)) have been studied by cyclic voltammetry (CV) in acetonitrile. The films are found to display pronounced and stable redox responses in solution. The reduction/reoxidation processes exhibit large splittings between the first two reduction and reoxidation waves. However, a pair of reversible oxidation and rereduction waves is observed after the reoxidation of a reduced film. The characteristics and the inter-relationship of these waves are uncovered by the CV technique, scanning electron microscopy (SEM), and UV/Vis-NIR spectra. A possible mechanism is proposed for the film electrode processes, which emphasizes the redox-induced structural reorganization of the metallofullerene film by the incorporation and expulsion of electrolyte ions into and out of the film. The influence of the counter ion diffusivity and the ion-pair stability on the electrochemical activity of the metallofullerene film has also been indicated.

“…Thus the second-order hyperpolarizability γ of the sample molecule can be estimated through the equation [1,28,29] γ = χ (3) N c L c (7) where N c is the number density of molecules and L c is the local field correction factor which equals [(n 2 0 + 2)/3] 4 .…”

Bis(tetrabutylammonium)bis(2-thioxo-1,3-dithiole-4,5-dithiolato)mercurate(II) was prepared and characterized by elemental analyses, electronic absorption, infrared and X-ray powder diffraction spectroscopy. The specific heat of the crystal was measured to be 1878.2 J.molK -1 at 300 K. The thermal decomposition process was investigated by means of thermogravimetric analysis and differential thermal analysis measurements in air together with infrared and X-ray powder diffraction spectra. The third-order nonlinear optical properties at 800 nm were measured by femtosecond optical Kerr gate technique by using CS 2 as reference. The third-order optical susceptibility of its acetone solution at the concentration of 9.27×10 -4 M was obtained to be 2.53×10 -14 esu. The second-order hyperpolarizability was estimated to be 1.7×10 -32 esu and the response time was about 226 fs. The third order nonlinear optical properties at 532 nm were investigated by using the Z-scan technique with 20 ps. It exhibited self-focusing effect and saturable absorption. The second molecular hyperpolarizability was estimated to be 8.4×10-32 esu.
