Their inherent chemical variability makes them especially intriguing for studies focused on organic-inorganic semiconductor heterostructures. A key aspect of TPcs is the substitutability of the central atom and the alterability of peripheral positions, like fluorination, which significantly impacts their ionization energy and affects energy level alignments in heterostructures (e.g. Ref. ) Notably, phthalocyanines are anticipated to exhibit weak interactions on van der Waals surfaces. Such interactions can be beneficial for customizing the electronic properties of TMDCs, since a strong interaction, accompanied by an integer charge transfer, would result in an undesirable localization of the charges at the interface.
