Novel series of peripherally phthalocyanines (Zn, Pd and Cu): Spectroscopic studies



A new series of metallophthalocyanines (MPc) containing metals such as : Zn (II), Cu (II) and, Pd (II) were designed, synthesized, and characterized, using MS, IR and UV-Vis spectroscopy. A Suzuki cross-coupling reaction was investigated by using the Pd(dppf)Cl2 as a catalyst and cesium carbonate as a base to improve the yield of the precursor 2.6-di(pyridin-3-yl)- phenyl benzyl ether. The changes of metals, substituents, and positions increases the Q-band value from the mono-substituted to the octa-substituted macrocycles, and from Pd, to Cu to Zn complexes. All MPc showed quite similar IR spectra.
