Example 2

Film UV-Vis absorption spectra of polymers from Example 2 were acquired on a Perkin Elmer Lambda 20 UV/VIS Spectrophotometer. All film samples were spin-cast on ITO/ZnO substrates. Solution UV-Vis absorption spectra at elevated temperatures were collected on a Perkin Elmer Lambda 950 UV/VIS/NIR Spectrophotometer. The temperature of the cuvette was controlled with a Perkin Elmer PTP 6+6 Peltier System, which is supplied by a Perkin Elmer PCB 1500 Water Peltier System. Before each measurement, the system was held for at least 10 min at the target temperature to reach thermal equilibrium. A cuvette with a stopper (Sigma Z600628) was used to avoid volatilization during the measurement. The onset of the absorption is used to estimate the polymer bandgap.

Cyclic voltammetry was carried out on a CHI760E electrochemical workstation with three electrodes configuration, using Ag/AgCl as the reference electrode, a Pt plate as the counter electrode, and a glassy carbon as the working electrode. Polymers were drop-cast onto the electrode from DCB solutions to form thin films. 0.1 mol L⁻¹tetrabutylammonium hexafluorophosphate in anhydrous acetonitrile was used as the supporting electrolyte. Potentials were referenced to the ferrocenium/ferrocene couple by using ferrocene as external standards in acetonitrile solutions. The scan rate is 0.1 V s⁻¹.

Film ultraviolet–visible absorption spectra were acquired on a Perkin Elmer Lambda 20 ultraviolet/visible Spectrophotometer. All film samples were spin-cast on ITO/ZnO substrates. Solution ultraviolet–visible absorption spectra at elevated temperatures were collected on a Perkin Elmer Lambda 950 ultraviolet/visible/NIR Spectrophotometer. The temperature of the cuvette was controlled with a Perkin Elmer PTP 6+6 Peltier System, which is supplied by a Perkin Elmer PCB 1,500 Water Peltier System. Before each measurement, the system was held for at least 10 min at the target temperature to reach thermal equilibrium. A cuvette with a stopper (Sigma Z600628) was used to avoid volatilization during the measurement.

All reagents were of the highest purity commercially available (≥97 %). All buffers were prepared with reagent grade materials or better. Bovine serum albumin (BSA) was from Thermo Fisher Scientific. Butyrylcholinesterase from equine serum and acetylcholinesterase from Electrophorus electricus were from Sigma-Aldrich. S-butyrylthiocholine and S-acetylthiocholine were from Alfa Aesar. Fmoc- and Boc-amino acids were from AAPPTec (Louisville, KY), and the amino acids were from Fisher Scientific and Alfa Aesar. Thin-layer chromatography and NMR spectroscopy were used to analyze amino acid analog purity. Absorbance measurements were made using a PerkinElmer Lamba 25 spectrophotometer fitted with a PCB-1500 water Peltier system (PerkinElmer) for temperature control. Cuvettes were from Starna Cells (Atascadero, CA). Water for all solutions was purified using a Barnstead Nanopure Diamond water system.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
