Synthesis of Polyacrylate‐Based Chalcone Containing Different Donor Moieties and Studies on their Optical, Electrochemical, and Thermal Properties

Abstract

Four novel metal-free acrylate polymers were synthesized via free radical polymerization using AIBN, in which a phenyl-chalcone-phenyl unit was connected with donor moieties such as fluorene, indole, anthracene, and benzophenone along with an acrylic acid group. The molecular weights of the polymers (P1-P4) were determined by gel permeation chromatography and their molecular structures were confirmed by FT-IR, 1 H-NMR and 13 C-NMR spectroscopy. The polymers were studied for their thermal properties by using DSC and thermo gravimetric analysis, which showed glass transition temperature (T g ,°C) in the range of 140-165°C. The relationship between molecular structure and optoelectronic properties of the synthesized polymers were investigated by UV-Visible, cyclic voltammetry, and electrochemical impedance spectroscopy.

Synthesis of Functionalized Flexible and Rigid Polyurethane for Oil Spill Treatment

“…In addition to an increase in the intensity of each of the (CH2) aliphatic peaks at (2866-2970) cm -1 , the carbonyl group (C=O) exhibits a shift from 1712 cm-1 to 1720 cm -1 , as well as an increase in its intensity. These values agreed very well with the results reported in the literature [29,30]. Fig.…”
