Abstract

Abstract New π-donors containing a pyrene or a tetrahydropyrene ring were synthesized by means of a unique transannular reaction of the corresponding [2.2]metacylcophane derivatives. The CT complexes of these donors with a series of TCNQ derivatives different in electron affinity were prepared, and their electrical conductivities on single crystals were measured. The highest conductivity (0.36 Ω−1 cm−1) was that of the tetrahydropyrene derivative-TCNQ complex. It was reconfirmed that the partial charge-transfer from a donor to an acceptor is very important for high conductivity.
