Objective: The short review summarizes old and more recent findings highlighting special features of polymerizations of heterocyclic monomers, which usually are not observed in processes leading to low molar mass products. These features include: Influence of the initial monomer concentration on its equilibrium concentration, role of monomer in determination of the relative reactivity of “free” ions and ion-pairs in Read More

Background: 4-Hydroxyquinolin-2-ones and quinoline-2,4-diones, a subset of the quinolone scaffold, have attracted attention due to their biological properties. These structures are present in many classes of natural products and pharmaceutical agents and show promise in antiviral and antibacterial treatment. They possess anticonvulsive effects, selective affinity to cannabinoid receptors, and other interesting biological Read More

Background: Organic pollutants are common and exist widely in ecosystems, particularly in aqueous solution, and they are a serious threat to humans. Many technologies have been applied to wastewater treatment, and adsorption is a good method for organic pollutant removal that has been universally applied. Cyclodextrins (CDs) are excellent adsorbents due to their unique cavity, which can form stable inclusion compl Read More

Background: 2-Substituted benzoxazoles and their various derivatives are very important structures of functional materials, such as natural products, drug candidates, and biologically relevant compounds. Furthermore, they are multifunctional intermediates and synthons in a large number of functional group transformations and total syntheses. In last several decades, chemists have put forth tremendous effort and Read More

Background: Chiral peroxides, many of which are biologically active, are an attractive target in organic synthesis. Organocatalysts have been used for some time in the asymmetric epoxidation of α,β- unsaturated carbonyls. More recently, cinchona-derived organocatalysts have been adapted to effect the asymmetric peroxidation of unsaturated ketones. We successfully applied this catalyst system to the stereoselective peroxi Read More

Background: In the quest for sustainable energy materials, new donor and acceptor materials are being designed, synthesized and tested for photovoltaic (PV) applications. In this context, conjugated organic polymers have received significant interests in the last few decades. Objective: In the present work, we synthesized an organic poly-yne P and assessed its efficiency as donor with a rylene acceptor EP-PTC. Methods: Th Read More
