New Julolidine substituted phthalocyanine dyes developed in this work exhibit being cost-effective and simple to produce. FTIR, MALDI-TOF, UV-visible, and NMR analysis verified the structural properties of the dyes. The dyes did not clump and were soluble in a wide range of organic solvents. The dyes ZnPc, NiPc, CoPc and CuPc are completely transparent in solution. The dye’s thermal stability and transmittance were measured using thermogravimetric analysis (TGA) and UV-visible spectroscopy. Among the other produced dyes, ZnPc (17%) spin-coated films had the lowest light scattering process and the maximum transmittance (83%) in the blue area. Finally, the combined results revealed that ZnPc dye might be employed as an LCD color filter.
