Electrochemical polymerization of some monomers with schiff's base structure. A voltammetric study

Abstract

The electrochemical polymerization of some Schiff's base‐type monomers like pyrrole‐2‐aldehyde azine, N,N′‐di(2‐pyrrolylmethylene)‐1,4‐diaminobenzene , and N,N′‐di(2‐pyrrolylmethylene)‐4,4′‐diaminobiphenyl proceeds as a precipitating polymerization to the anodic compartment. The voltammetric study of monomers and polymers using Pt electrodes and paste‐carbon electrodes were carried out. The results are in agreement with the MO calculations using the Hückel approximation for evaluating of the reactivity of the monomers.

Electrochemistry and photoelectrochemistry of two donor–acceptor polythiophene polymers with acceptor moieties in the main chain

“…Synthesis and electropolymerization of a series of related oligothiophene-1,10-phenanthrolines have been also described [23], but again without detailed electrochemical investigation. As for the second polymer, poly(BT-azine), to the best of our knowledge it was not described before, but there have been several studies of various related polymeric thiophenoazines and azomethines in the literature [24][25][26][27][28], including electropolymerized ones [25,26]. However, as in the case of poly(BT-phen), no detailed studies of the nature of the observed redox-transitions were reported.…”

Synthesis, characterization and electrochromic properties of a conducting copolymer of pyrrole functionalized polystyrene with pyrrole

“…where R is an aromatic residue and Ox is an oxidizable group as 2-pyrrolyl, 2-thienyl or 1-naphthyl [36,37]. By chemical or electrochemical polymerization, polymers containing 2,2 0 -bipyrrolediyl or 2,2 0 -thienyldiyl rings or 1,1 0 -binaphthyl in the main chain, spaced by conjugated sequences containing azomethine units, are obtained.…”

Electroactive and bioactive films of random copolymers containing terthiophene, carboxyl and Schiff base functionalities in the main chain

“…29,30 Aromatic polyazomethines can be obtained by different chemical procedures: classical polycondensation between aromatic/ heterocyclic dialdehydes with aromatic/heterocyclic diamines; [18][19][20][23][24][25] self-polycondensation of an automer; 32 and polymerization of monomers containing preformed azomethine linkages. 22,[29][30][31][32][33][34][35][36] Among these synthetic approaches, the one employing monomers that contain preformed azomethine bonds seems to be more versatile, provided that it permits the introduction in the conjugated main chain of different moieties (e.g. thienyl, pyrolyl, naphtyl and aryl) or well-defined polymeric side chains in a controlled manner, thus allowing for a fine tuning of the electrical and/or optical properties of the final materials.…”
