Phthalocyanine (Pc) exhibits excellent thermal, chemical, and physical stability, as well as outstanding absorption and emission properties, which are useful for its application in the fields of color filters, chemosensors, and photosensitizers. However, unsubstituted Pc is insoluble in common organic solvents due to its inherent intermolecular aggregation behavior, and thus needs to be finely dispersed in the presence of dispersants before use. In this article, we present a new Pc derivative, prepared by attaching long aliphatic groups at peripheral positions of Pc, which shows high solubility in most nonpolar solvents, leading to good optical properties. For its synthesis, dodecanyl-zinc Pc (dodecanyl-Zn-Pc) was prepared via direct tetramerization, starting with 4-dodecanyl phthalonitrile as the intermediate. Various characterization techniques were employed to estimate the structural and optical features of dodecanyl-Zn-Pc, including $^1H$ nuclear magnetic resonance, matrix-assisted laser desorption/ionization, and ultraviolet-visual spectrophotometry and fluorimetry. In addition, the morphology of dodecanyl-Zn-Pc film was examined by polarized optical microscopy.
