Ferrocene clicked polypyrrole derivatives: effect of spacer group on electrochemical properties and post-polymerization functionalization

“…Amplification of the polarization potential beyond 1.0 V resulted in a steady increase in the current density indicating formation of radical cation of pyrrole unit. [29,30] Such behavior is in accordance with literature [31][32][33] and Py4N 3 as seen in Figure 1(c). Starting from the second scan (Figure 1(d)), a new quasi…”

Multichromic polymers based on pyrene clicked thienylpyrrole

“…Propargyl‐pyrene was easily synthesized in a one‐pot reaction with ca 50% yield by the reaction of 1‐pyrenylmethanol with propargyl bromide in the presence of NaH. SNS‐N 3 was used as the azide functionalized partner and a typical click reaction in the presence of CuSO 4 and sodium ascorbate in acetone/water as the solvent system was performed (Scheme ). The monomer (SNS‐pyrene) was fully characterized by 1 H NMR (Fig.…”

“…1‐Pyrenemethanol, 1,4‐dioxane, NaH, propargyl bromide, methanol, dichloromethane (CH 2 Cl 2 ), NaSO 4 , hexane, ethyl acetate, tetrahydrofuran (THF), CuSO 4 .5H 2 O, sodium ascorbate, thiophene, succinyl chloride, ethanolamine, p‐toluene sulfonic acid, triethylamine, dimethylaminopyridine, p‐toluene sulfonyl chloride, sodium azide, EDOT and acetonitrile (ACN) were used as received. 1,4‐di(2‐thienyl)‐1,4‐butanedione, 2‐(2,5‐di‐thiophene‐2‐yl‐pyrrol‐1‐yl)‐ethanol, toluene‐4‐sulfonic acid 2‐(2,5‐di‐thiophen‐2‐yl‐pyrrol‐1‐yl)‐ethyl ester and 1‐(2‐azido‐ethyl)‐2,5‐dithiophen‐2‐yl‐1H‐pyrrole (SNS‐N 3 ) were synthesized according to the literature …”

Click Chemistry: A Powerful and Versatile Methodology for Preparation of Ferrocene-Containing Polymers

“…The first one is first electrochemical polymerization of 1-(2-azidoethyl)-2,5-di-thiophen-2-yl-1H-pyrrole (3) to yield PSNS-N 3 (P15) films on ITO electrodes. Afterward, the PSNS-N 3 coated ITO electrode was reacted with 2 in the presence of CuSO 4 and sodium ascorbate, and the PSNS-Fc (P16) coated electrode was obtained with potential usages as electrocatalysts, biosensors, and gas sensors [45]. Another strategy is first to perform the CuAAC of 3 and 2, then electrochemically polymerized the precursor monomer of SNS-Fc (4), and PSNS-Fc films on ITO electrodes were finally prepared [46].…”
