Metal-free phthalocyanine (H 2 Pc) has been widely used as photosensitive semiconductors in the organic optoelectronics field because of its unique planar molecular structure and high photocarriers’ generation efficiency. Herein, this paper related to a new facile and efficient one-step method for preparing specific crystal form of H 2 Pc with high crystallinity through ball-milling process, in which α-H 2 Pc can be prepared directly by dry ball-milling, and β-H 2 Pc and X-H 2 Pc can be simply obtained through wet ball-milling in butanone solvent at different temperatures. X-ray diffraction (XRD) was used to characterize the crystal stability of α-H 2 Pc, β-H 2 Pc, and X-H 2 Pc, which revealed that all the three crystalline H 2 Pc prepared had excellent crystal stability under different mechanical conditions. Graphical abstract α-H 2 Pc, β-H 2 Pc, and X-H 2 Pc with excellent crystal stability can be simply prepared by dry/wet ball-milling process.
