“…Aromatic poly(azomethines) ( PAMs ), also known as poly(imines) or Schiff base polymers are conjugated networks with interesting characteristics such as high thermal stability, semiconductivity, or optoelectronic properties which make them attractive candidates for electronic and optoelectronic devices, such as photovoltaic cells, light‐emitting diodes, or thin‐film transistors . However, the high rigidity of these aromatic polymers and the poor solubility in organic solvents has limited their practical applications.…”

A conjugated crosslinked polyazomethine containing pyridine units (PAM-Py) was prepared from two commercial monomers, 2,6-diaminopyridine and isophthaldehyde, under microwave heating in only 30 min. Taking advantage of its thermal and chemical stability, porosity (S BET of 192 m 2 /g), insolubility, and ability to coordinate metals through the pyridine or imine N atoms, ruthenium-, aluminum-, iron-, and cobalt-poly(azomethine-pyridine) complexes (PAM-PyM) were prepared. The resulting metal polymers were evaluated as heterogeneous catalysts for the cycloaddition of CO 2 to epoxides yielding selectively the corresponding cyclic carbonates. All heterogeneous catalysts showed an extraordinary effectiveness with very high yields of epoxide conversion (up to 98%), turnover numbers up to 7425, and were reused at least five times without loss in catalytic activity.

This review summarizes recent progress in synthetic methodologies of chelating polymer ligands such as linear, branched, cross‐linked, grafted polymers, polymer films, liquid crystal polymers, dendrimers, star‐shaped and hyperbranched polymers. The features of methods for producing chelating polymer ligands are considered in detail: free‐radical (co)polymerization, living/controlled radical, metathesis, grafted, chemical oxidized, microwave‐assisted and asymmetric polymerization, electropolymerization, cyclopolymerization, polycondensation, post‐polymerization modification, click chemistry methods and “green” synthesis. The main directions of the development of synthetic chemistry of chelating polymeric ligands are analyzed. The bibliography includes works published in the last five years.

“…Aromatic poly(azomethine)s (PAzM)s are polycondensed materials of high performance with interesting mechanical and thermal properties. Likewise, most of them show electronic, linear, and nonlinear optical behavior due to their extended π‐conjugated structure . Many applications as a metal support for heterogeneous metal catalyst have been reported due to their strong ability to form chelates and for PAzMs or oligomeric PAzMs composed by rigid moieties and long flexible segments, applications in the crystal liquid field have also been studied .…”

Three new diamines derived from epoxide compounds were synthesized. The preparation of diamine monomers implied the reaction between a phenoxyalkyloxirane (alkyl: H, methyl, isopropyl) and bisphenol A, obtaining the respective aliphatic diols, which produced the corresponding dinitro derivatives. Finally, these derivatives were reduced by using palladium/carbon activated as catalyst and hydrazine as a hydrogen source. Then, six oligomeric poly(ether-azomethine)s (PEAzMs) were obtained from a polycondensation reaction between the new diamines and bis(4-formylbiphenyl-4-yl)dialkylsilane (alkyl: methyl, phenyl) with 84-93% yields. The structural characterization of the diamines and PEAzMs was performed by elemental analysis, infrared spectroscopy, and nuclear magnetic resonance spectroscopy ( 1 H, 13 C, and 29 Si). Furthermore, polymers were analyzed by solubility tests, gel permeation chromatography, ultraviolet-visible (UV-vis) spectroscopy, thermogravimetry, and differential scanning calorimetry analysis. The results showed PEAzMs with 2-11 repetitive units, where the design of the monomers allowed to obtain improved solution processability in comparison with previously reported silylated poly(azomethine)s and good thermal stability. Additionally, all samples showed high transparency in the UV-vis region.
