SYNTHESIS AND IR-SPECTROSCOPIC ANALYSIS OF A HIGH-INTENSITY NICKEL PHTHALOCYANINE PIGMENT CONTAINING NITROGEN AND SULFUR

Abstract This study reports the synthesis of a high-intensity nickel phthalocyanine pigment containing nitrogen and sulfur, characterized by the incorporation of macroheterocyclic structures. The pigment was comprehensively investigated to assess the role of macroheterocyclic frameworks in enhancing its optical and structural properties. The absorption regions were analyzed using modern physicochemical techniques based on IR spectroscopy. The results confirmed that the cyclic bonding patterns contribute to the formation of a complex structural framework, providing new insights into the structural characteristics and potential applications of nitrogen- and sulfur-containing nickel phthalocyanine pigments.
