Used as an intermediate in the synthesis of fluorinated phthalocyanine dyes and pigments, which exhibit high thermal and chemical stability. These compounds are applied in specialty coatings, optoelectronic devices, and as n-type semiconductors in organic electronics due to their electron-accepting properties. The strong electron-withdrawing nature of the perfluorinated chain enhances performance in photovoltaic cells and sensors. Also employed in the development of advanced materials for nonlinear optics and laser technologies.
