Phthalocyanines and their metallo derivatives (MPcs) have recently attracted an increasing interest not only for the preparation of dyes and pigments but also as building blocks for the construction of new molecular materials for electronics and optoelectronics. Numerous properties arise from their electronic delocalization, which makes them valuable in different fields of science and technology such as photoconducting agents in photocopying devices, chemical sensors, electrocatalyst, data storage systems, liquid crystals and photosensitizer in photodynamic therapy. [1-2] Dyestuffs containing carboxylic group are advantageous because they can be anchored onto the hydroxyl-bearing oxide surface. [3] Carboxyl-bearing metallophthalocyanines have been studied in terms of photophysical and photochemical properties in homogeneous solutions and in micellar systems. [4] In this work, our aim has been the synthesis of carboxylic acid containing metallophthalocyanines (MPc; M= Zn, Cu, Co) by cyclotetramerisation of the phthalonitrile and characterized by elemental analyses, FTIR, 1 H NMR, UV–vis and MALDITOF MS spectral data.
