2,9,16,23-Tetracarboxyphthalocyaninatomagnesium(II) [Mg(II)-taPc] films were obtained on indium/tin oxide (ITO) coated glass electrodes by electrodeposition, using MgCl2, CaCl2, CoCl2, or ZnCl2as a supporting electrolyte. The electrical properties of junctions between electrodeposited Mg(II)-taPc film and aluminum electrode were evaluated by current-voltage measurements. The diode based on Mg(II)-taPc film containing Mg2+as a bridging metal ion exhibited Zener-type breakdown, while the diode based on Mg(II)-taPc film containing Ca2+or Zn2+as a bridging metal ion showed almost symmetrical I–V. The diode based on Mg(II)-taPc film containing Co2+as a bridging metal ion was electrically unstable. The diode based on Mg(II)-taPc film containing Mg2+, Ca2+, or Zn2+as a bridging metal ion exhibited a photocurrent on forward biased condition. |
