We have developed a nanoscale electrocrystallization that enables site-selective growth of organic nanocrystals under ambient conditions. By applying an AC electric field between two electrodes on a substrate immersed in a raw material solution, localized crystallization can be induced. The resulting materials are crystalline with potentially ordered molecular arrangements. This method, requiring no high temperatures or vacuum, offers a promising approach for green nanofabrication.Recently, we have applied this method to magnesium(II) phthalocyanine (Mg(Pc)) to develop novel nanocrystalline materials. Using tetrahydrofuran (THF) as the solvent and various tetrabutylammonium (TBA) salts as supporting electrolytes, we successfully obtained several Mg(Pc)-based microcrystals under different conditions.This presentation will discuss the morphology and fabrication conditions of Mg(Pc)-based microcrystals formed with different TBA salts, as well as their potential for device applications.
