Synthesis of nonperipherally tetra-[5-(diethylamino)-2-formylphenoxy] substituted metallophthalocyanines and their electrochemistry

Abstract

3-(5-(Diethylamino)-2-formylphenoxy)phthalonitrile (n-TY-CN), metallophthalocyanines n-TY-Co, n-TY-Cu, n-TY-Mn bearing (5-(diethylamino)-2-formylphenoxy) groups at nonperipheral positions were prepared for the first time. These compounds were characterized with IR, NMR (only for n-TY-CN), mass and UV-Vis (except n-TY-CN) spectroscopy. Voltammetric characterizations of n-TY-Co, n-TY-Cu, n-TY-Mn revealed that while n-TY-Co, n-TY-Cu, n-TY-Mn showed characteristics Pc ring and/or metal based reduction reaction, n-TY-Co, n-TY-Cu, n-TY-Mn were coated on the working electrode during the oxidation processes owing to the cationic electropolymerizations of the (5-(diethylamino)-2formylphenoxy) substituents.

“…On the other hand, NMR spectra of DFP‐Cu and DFP‐Mn could not be obtained owing to paramagnetic Cu (II) and Mn (III) ions. [ 36,37 ] Finally, the molecular ion peaks of DFP‐Si, DFP‐Cu, and DFP‐Mn were observed at 963.14 [M] + (Figure 3a), 1417.45 [M] + (Figure 3b), and 1443.32 [M] + (Figure 3c) m/z respectively, in mass spectra.…”
