Recent developments on thermally convertible soluble precursors of copper phthalocyanine (CuPc), which can be potentially useful for fabrication of a variety of organic devices, have been reviewed. Reaction of phthalonitrile with lithium alkoxides under mild conditions successfully yielded a series of soluble CuPc precursors (4a–4d). X-ray crystallography clarified that the conjugated skeletons of these are all isostructural, and have two alkoxy groups in a syn-conformation fashion, leading to highly bent structures. Thermal analyses demonstrate that these precursors are quantitatively converted into insoluble CuPc with increasing the temperature, in which the conversion temperatures are dependent on the crystal structures of the samples.
