1. Singlet fission in functionalized pentacene compounds has been observed experimentally. 2. Intramolecular singlet fission in covalently linked pentacene and tetracene dimers has also been reported. 3. This pentacene oxidation technique is akin to the silicon oxidation used in the silicon electronics. 4. Acenes, Pentacene and Tetracene in particular, are a prominent candidates for singlet fission. 5. Subsequently, single pentacene molecules were detected in " p "-terphenyl crystals. 6. Using an atomic force microscope every single atom and bond of a pentacene molecule could be imaged. 7. One of them, pentacene , conducted electricity well enough that it might be fashioned into a transistor. 8. Oligomers and polymers based on pentacene have been explored both synthetically as well as in device application settings. 9. Thin films of cross-linked PVP can be used in this application, often in combination with pentacene . 10. "' Pentacene "'is a polycyclic aromatic hydrocarbon consisting of five linearly-fused benzene rings.
