In our previous study, we demonstrated that magnesium(II) phthalocyanine (Mg(Pc))-based nano- and bulk crystals could be fabricated via electrochemical methods using tetrabutylammonium salts, specifically TBA·BF₄ or TBA·ClO₄, as supporting electrolytes. Furthermore, the conductivity at room temperature of the bulk crystals was estimated from their current-voltage (I-V) characteristics, revealing high conductivity in all cases. In this study, we investigated the field-effect characteristics of nanocrystals obtained with TBA·BF₄ or TBA·ClO₄. Additionally, we conducted the X-ray structure analysis of bulk crystals obtained with TBA·BF₄. In this presentation, we will discuss not only the electrical properties of these nanocrystals but also the structural aspects of the bulk crystals.
