Abstract:
The present invention relates to a novel preparation method of a benzoporphyrin derivative and the fabrication of an organic thin-film transistor thereby. The novel preparation method of the benzoporphyrin derivative by the present invention remarkably reduces the number of production processes compare to existing preparation method of the benzoporphyrin derivative for economically obtaining the benzoporphyrin derivative which is a target compound. The process is simplified and the facility and production costs for applying the printing method are reduced by dissolving the benzoporphyrin derivative in more than two kinds of mixed organic solvent with different boiling points, and fabricating the organic thin-film transistor using the printing method.
