Trombach, N. published the artcileSynthesis and electropolymerization of pyrrol-1-yl substituted phthalocyanines, HPLC of Formula: 50966-69-3, the main research area is pyrrolyl alkoxy phthalocyanine monomer preparation cyclotrimerization substitution; polypyrrole phthalocyanine preparation oxidative polymerization isolated electroactive group; redox potential electrochromism polypyrrole phthalocyanine conducting polymer.
Metal-free and Zn, Co, Ni – 2,9,16,23-Tetrakis(2-pyrrol-1-yl-alkoxy)phthalocyanines, in which the phthalocyanine is connected via an alkylene spacer to a pyrrole substituent, were prepared via three step reaction sequence to obtain monomers with groups for electropolymerization electronically isolated from the phthalocyanine. The synthesis sequence involves cyclotrimerization, substitution of NO2 groups with OH groups, then conversion to the phthalocyanine ring by the Li pentanolate method. Electrochem. oxidative polymerizations were carried out either under potentiodynamic conditions by scanning between 0.1 and 1.4 V vs. SCE at scan rate of 10 mV s-1 or at a fixed potential of 1.4 V vs. SCE. Polypyrrole films of thickness up to 5 μm were obtained on ITO electrodes. The UV/Vis spectra show the presence of phthalocyanine and polypyrrole structural units in the polymers. The charge-discharge redox process of the conducting polymers is accompanied by a reversible electrochromic color change. The polypyrrole-phthalocyanine films exhibit specific elec. conductivity of ∼10-5 S-cm-1.
