Supported molybdenum schiff base derivated from 2-aminopyridine on oxidized cellulose: synthesis, characterization, and catalytic application

Among the natural material, cellulose is the most abundant biopolymer on Earth providing mechanical strength to plants. It has been used by humans for thousands of years as paper and textiles. Recently, the functionality of cellulose has been increased by hybridization with different materials such as different ligands and nanoparticles which it has drawn much interest in the fields of flexible electronics, biosensors, and drug delivery applications. In these micro hybrid materials, cellulose acts as an ubiquitous and biofriendly substrate for these modern applications [1-2]. Molybdenum schiff-base complex are every important material for using in medicinal inorganic chemistry due to their diverse biological and pharmacological antitumor activities. Also, schiff-bases have gained much importance in biomimetic modeling applications and designing molecular. Schiff bases are used as catalysts, intermediates in organic synthesis, dyes, pigments, polymer stabilizers, and corrosion inhibitors [3].Herein, micro cellulose was extracted from Carthamus tinctorius and oxidized by sodium periodate. Molybdenum schiff base complex derivated from 2-amino pyridine was immobilized on this natural biopolymer. The catalytic properties of it were considered as a heterogeneous catalyst in the oxidation of organic compounds such as alcohols.
