Lett. 83, 1252 (2003); 10.1063/1.1600848Effect of the disorder/order phase transition on the electrical and photoelectrical properties of C 60 thin films Using a new kind of organic complex system of electrical bistability for ultrahigh density data storage A novel C 60 -DDME complex thin film was prepared by a new modified vacuum deposition technique. Stable and reproducible electrical bistable properties are observed in the C 60 -DDME thin films. The structure and spectroscopy characteristics of the complex C 60 -DDME thin film are considerably different from those of both DDME and C 60 thin films, as is revealed by high resolution scanning electron microscopy, x-ray diffraction, and ultraviolet-visible absorption spectra.

“…Among the fullerenes, C 60 has been the most widely studied due to its elegant molecular symmetry and intriguing structural, dynamic, and electronic properties. − Recently, there has been great interest in the development of C 60 -based materials because they display a rich variety of solid-state properties such as superconductivity, magnetic ordering, nonlinear optical properties. It is known that C 60 has strong electron-transfer interactions with donors. , The substantial complexation of a donor with C 60 results not only from a strong charge transfer (CT) interaction but also from the fact that the donor molecule is able to cover closely the C 60 molecules .…”

For this purpose, a lot of planar donors, such as tetrathiafulvalene, dithiadiazafulvalene, tetrathiotetracene, and pyranylidene families, have been widely investigated for the formation of donor−acceptor contacts with C 60 . , These molecules are rather weak donors, with ionization potentials (IP) of 5.7−7.1 eV, and form CT complexes with C 60 at different CT rates.…”
