A BF(2) complex containing an octafluorotetracene moiety was synthesized as a new type of electron acceptor. This compound exhibits long-wavelength absorption based on the perfluorotetracene skeleton and high affinity due to its quadrupolar structure enhanced by fluorination. In crystal, molecules are arranged with short F...pi F...F contacts affording dense crystal packing. The exhibited n-type semiconducting behavior.
