Synthesis, Crystal Structure, and Electron-Accepting Property of the BF2 Complex of a Dihydroxydione with a Perfluorotetracene Skeleton
摘要:
A BF2 complex containing an octafluorotetracene moiety was synthesized as a new type of electron acceptor. This compound exhibits a long-wavelength absorption based on the perfluorotetracene skeleton and high electron affinity due to its quadrupolar structure enhanced by fluorination. In the crystal, the molecules are arranged with short F...pi and F...F contacts affording a dense crystal packing. The BF2 complex exhibited n-type semiconducting behavior.
