Functionalized polythiophene for corrosion inhibition and photovoltaic application

Abstract: Conjugated polymers are encouraging substitute for creating clean and renewable energy for photoinduced charge generation and transport media in polymer solar cells (PSCs). Successful synthesis of a new solution processable n‐type polythiophene based π‐conjugated polymer (P3HT‐CN) is done where polythiophene units are substituted by cyano groups through post functionalization approach of synthesized P3HT which is cheap, stable, easily prepared, and inert against ambient conditions and is expected to be a compe… Show more

“…The –NH 2 group is then converted to diazonium ion (–N 2 + ) through reaction with nitrite. Then, using Sandmeyer’s reaction, the diazonium ion is substituted with –CN using copper (I) cyanide [ 144 ]. PT functionalization through electrophilic bromination was also explored.…”

“…The 1 H-NMR spectrum of HTB-co-P3HT (Figure 1C) is very different in appearance from that of HTB. The signal at 0.88 ppm is assigned to the CH 3 -of the hexyl group, the multiplets at 1.28-1.56 ppm and 2.57-2.80 ppm are attributed to the methylene protons from the hexyl group while the thiophene groups are signaled at 7.01 ppm (Mota et al, 2021;Yadav et al, 2021).…”

“…As suggested by Bockris and Swinkels [8], this inhibition is caused by the great affinity of sulfur atom to the metal and it is easily adsorbed on the metal surface by removing the water molecules readily existing on that surface. Thiophenes and related compounds containing functional electronegative groups such as nitrile group and π-electrons in triple or conjugated double bonds are usually good inhibitors [9]. For example, a new benzothiophene-3-carbonitrile derivative has been reported as an effective copper corrosion inhibitor in hydrochloric acid.…”
