Phthalocyanines containing the 18-π electron system that are used in a number of applications because of their architectural flexibility, high chemical stability, good spectroscopic characteristics and diverse coordination properties are rich porphyrin analogs derived from four isoindole units [1]. Numerous properties arise from their electronic delocalisation, which makes them valuable in different fields of science and technology [2]. Since the discovery of phthalocyanines (Pcs), many scientists have sought to synthesize and design the most suitable molecules for a variety of applications, such as display devices, chemical sensors, biological imaging, catalysts and photosensitizers for photodynamic therapy (PDT) [3]. In this work, we have demonstrated the synthesis of new axially di-substituted silicon(IV) and peripherally tetrasubstituted zinc(II) phthalocyanines containing carboxylic acid derivatives. All complexes were characterized using UV–Vis, FTIR, 1H-NMR, MALDI-TOF MS as well as elemental analysis spectral data.
