Abstract:
A condensation compound of a fluorinated cyclopentane ring and an aromatic ring, which is useful, for example, for electronic materials, and a process for producing the same are provided. For instance, according to Scheme 1 below, a compound (68) containing a condensed structure formed of a hexafluorocyclopentane ring and an aromatic ring is synthesized. The aromatic ring is not limited to a thiophene ring but can be any ring and any substituent can be used. Thus a compound containing a condensed ring structure formed of a hexafluorocyclopentane ring and an aromatic ring, particularly, for instance, a thiophene ring, which was impossible to produce conventionally, can be produced easily with high yield. The compound of the present invention is particularly suitable to be applied to, for example, electronic materials or semiconductors. When it is polymerized and thereby the π-electronic conjugation is extended, it also is expected to be applied to, for example, n-type organic semiconductors and molecular wires that are indispensable for developing molecular electronics elements.
