Dithallium phthalocyanine (Tl2Pc) has been synthesized from pure Tl metal a
nd o-phthalodinitrile. The isolated compound was characterized by elemental
analysis, X-ray powder diffraction, electron diffraction and EDX spectrosc
opy. Based on these results, the compound synthesized by the present method
was concluded to be Tl2Pc. The electrical conductivity of this powdery Tl2
Pc was measured and it exhibited the semiconductive property, in contrast w
ith a previous report. Copyright (C) 1999 John Wiley & Sons, Ltd.
