Synthesis, molecular and optical characterization of polycarbonates containing azobenzene side‐chains

Abstract

In this study, we report the synthesis and holographic characterization of polycarbonates containing an azobenzene group in their side‐chains. The polycarbonate (DR‐PC) was synthesized by the polyaddition reaction of Disperse Red 19 (DR 19) and carbon dioxide in N‐methyl‐2‐pyrrolidone for 24 h in air, and we investigated the mechanism in the presence of potassium carbonate. The film of polycarbonate was obtained by casting onto a slide glass in N,N‐dimethylformamide. The diffraction efficiency of the polycarbonate film was measured as a function of time and intensity of the induced laser. Independently of the intensity of the writing beam, the maximum diffraction efficiency in all DR‐PC films reached about 0.25%. Copyright © 2006 Society of Chemical Industry

Synthesis and Electrochemistry of Schiff Base Cobalt(III) Complexes and Their Catalytic Activity for Copolymerization of Epoxide and Carbon Dioxide

“…IR (KBr): 1 749 (s, C¼O), 1 609 (w, Arring), 1 580 (w, N¼O), 1 531 (w, Ar-ring), 1 314 (s, N¼O), 1 235 cm À1 (s, C-O). 1 …”

“…[1,2] The mechanical properties are predominated by the stereostructure of the region selectivity of the linear carbonate linkage in the polycarbonate. The enantioselectivity of the polycarbonate, head-to-tail connectivity, and carbonate linkage are important factors to determine the thermal stability and the mechanical properties.…”
