  摘要：

  pi-Conjugated electrically conducting polymer chelate ligands, poly(6,6'-dimethyl-2,2'-bipyridine-5,5'-diyl) (P6MeBpy) and poly(6,6'-dihexyl-2,2'-bipyridine-5,5'-diyl) (P6HexBpy), react with [Cu(CH3CN)(4)]X (X=BF4, ClO4) to give the corresponding semiconductive copper(I) complexes. The P6HexBpy-CuBF4 complex exhibits an MLCT absorption at 469 nm (epsilon=3300 M(-1) cm(-1)). The cyclic voltammogram of a film of the P6HexBpy-CuBF4 complex laid on a Pt electrode shows reversible redox peaks with an E(0), value of 0.59 V versus Ag+/Ag due to a Cu(II)/(I) couple, whereas, in the reduction region, the film of the complex exhibits an electrochemically active cycle at E(0) of -1.84 V attributable to a Cu(I)/(0) couple. The redox process at -1.84 V is accompanied by a color change of the film from orange to dark red. These UV-Vis and electrochemical data of the P6HexBpy-CuBF4 complex are discussed by comparing them with data of monomeric model complexes, [Cu(bpy)(2)]BF4, [Cu(dmebpy)(2)]BF4 and [Cu(dhexbpy)(2)]BF4 (dmebpy=6,6'-dimethyl-2,2'-bipyridine; dhexbpy=6,6'-dihexyl-2,2'-bipyridine).

  2-pyridyl rings, especially at the 6- or 3-positions, which can block the donor-N or Lewis acid Bi sites. Electron withdrawing groups (like CF3 or Br) can also severely reduce their ability to act as ligands to metal ions by reducing the electron donating ability of the pyridyl-N atoms. Noninnocent character is found in the reactions with Cu+ and Cu2+, resulting in the coupling of pyridyl groups to form
