The synthesis, physical properties, and structure of triisopropylsilylethynyltetracenodifuran (2) and pentacenodifuran (3) derivatives were reported. There showed high stability in solution in the dark, yet decomposed under light. Single crystal of pentacenodifuran was analyzed by X-ray diffraction analysis, and showed one dimensional packing array along the c-axis. The molecules were stacked with...
Highly soluble pentacene precursors possessing ketal bridges across the rings were synthesized. Pure pentacene was produced through thermal dissociation, while carbon dioxide and ethylene were extruded as volatile fragments. Thin solid film of pentacene can be prepared from these precursors by spin-coating method, followed by heating. Typical OTFT characteristics were observed from the devices prepared...
