Abstract

Abstract: The diacid salt,(H₂TAAB)(BF₄)₂ was synthesized from o-aminobenzaldehyde or self-condensation products of o-aminobenzaldehyde. Reaction of(H₂TAAB)(BF₄)₂with CuCl forms the complex Cu(Ⅰ)(TAAB)(BF₄). Metathesis between lithium tetracyanoethylene with Cu(TAAB)(BF₄)₂ yields the complex Cu(Ⅰ)(TAAB)(TCNE). It is a poor conductor with powder conductivity<10^-10S·cm^-1. The cyclic voltammetric studies have been carried out on Cu(Ⅱ)(TAAB)(BF₄)₂ complex and show a nearly reversible one-electron redox process at E_1/2= +0.0651 Vversus saturated calomel electrode.

Key words: TAAB macrocyclic, Copper complex, Redox property, TCNE charge-transfer salt, Conductivity
