Special Issue Information

Dear Colleagues,

Polymer-immobilized catalysts have advanced widely over the past years. The recent development of polymer-based catalysts caused the identification of numerous highly active catalysts, which are, however, still far less known than metal/metal oxide catalysts. The polymeric catalysts were efficiently used in various applications such as the photocatalytic degradation of organic pollutants (e.g., dye, drug, and other organic compounds) and organic reactions. The polymer-immobilized catalysts have higher catalytic activities and stereoselectivities compared with their corresponding low-molecular-weight catalysts in homogeneous solution systems. The heterogeneity of the organic reaction using polymeric catalysts gives great advantages in the synthetic process.

This Special Issue welcomes both review and original research articles on all aspects of polymer-supported and polymer-immobilized catalysts in the organic reactions and the degradation of organic pollutants.

The Special Issue will focus on, but is not limited to, polymer-supported and polymer-immobilized catalysts and applications for:

  1. Design of novel polymer-based nanocomposite in organic reactions.
  2. Design of novel polymer-based nanocomposite for removal of organic pollutants.
  3. Design of novel polymer/inorganic nanoparticle nanocomposites and their application in the environment.
  4. Polymer/Enzyme Composite with good catalytic activity.

An eco-friendly biocatalyst was constructed in three steps. In the first step, the tosylated starch (TsST) was synthesized by using a 4-toluenesulfonyl chloride. In the second step, the aminated starch was synthesized via the reaction of TsST with para-phenylenediamine. In the third step, the magnetic biocatalyst was fabricated by an in situ coprecipitation process from ferric and ferrous salts in the existence of aminated starch (AST). The biocatalyst was characterized by 1H NMR, EDX, FESEM, FTIR, VSM, and TGA analyses. The magnetic aminated starch (MAST) was used as a biocatalyst for the synthesis of 4-[(indol-3-yl)-arylmethyl]-1-phenyl-3-methyl-5-pyrazolone derivatives. The various products were prepared in noteworthy yields (85–93%) in fast reaction times (35–80 min) without laborious work-up procedures. The anticancer evaluation of some 4-[(indol-3-yl)-arylmethyl]-1-phenyl-3-methyl-5-pyrazolones derivatives was studied on the survival rate of breast cancer cell lines (MCF-7) and human fibroblast cells by using an MTT assay. Additionally, recovery of the biocatalyst was studied, and results showed that the MAST was easily isolated from the reaction flask and could be recycled for up to six consecutive cycles without meaningfully falling in its efficiency.
