“…In the absence of H 2 O 2 ( Figure 2A ), both electrodes have some redox peaks during the anodic scan and cathodic scan. These peaks are due to the oxidation and reduction of some substances possessing electrochemical activity in Erycibe obtusifolia extracts, such as flavonoids ( Cai et al, 2020 ), pigments ( Pearce et al, 2020 ), carotenoids ( Čižmek and Komorsky-Lovri ), etc.…”

Peroxidases are species-specific. Differences in peroxidase can objectively reflect the genetics among species. The use of peroxidase to assist in species identification is relatively simple and effective. In this work, we proposed a graphene-modified electrode. This electrode can amplify the signal of electrocatalytic reduction of hydrogen peroxide. Since peroxidase can catalyze the reduction of hydrogen peroxide, this signal can be used as an indicator to demonstrate the content of peroxidase in different plant tissues. Twelve herbal medicines were selected for our study. The results show that this electrochemical-based detection technique was comparable to colorimetric method in terms of accuracy.

“…PTEs are soluble in a variety of polar organic solvents, making them a good candidate for green solvent processing. To date, PTEs have been explored as an alternating unit in a polymeric acceptor material for OPVs [19], as a supramolecular nanostructure in water by use of ethylene glycol units on the ester positions [20], as a fluorescent probe [21], and for the development of fundamental structure-property relationships [22,23]. Bay N-annulated PTEs have been explored for their liquid crystallinity, however, this only includes alkyl chains of C6, C8, C10, and C12 on the ester positions [24,25].…”

Herein, we report on the design and synthesis of an N-annulated perylene butyl tetraester (PTEN-H) for use in alcohol processed semiconducting films. PTEN-H was contrasted with the known N-annulated perylene diimide (PDIN-H) where the former has ring-opened imide positions which in turn lowers the electron affinity (i.e., rendering hole transporting) and improves polar green solvent solubility. PTEN-H can be solubilized in 1-butanol up to 10 mg/mL with gentle heating and can be spin-cast or slot-die coated to form uniform thin films on glass and/or plastic substrates. Organic field-effect transistors (OFETs) were fabricated using PTEN-H in the active material layer which was deposited from solution using 1-butanol as the solvent. While hole mobilities were achieved (0.39 x 10-4 cm2/Vs), blending the molecular material with a previously reported green solvent processable semiconducting polymer, IIG20-OH, was done to boost performance. This led to increased mobilities for not only the native molecular PTEN-H material, but for the native IIG20-OH polymer as well. Furthermore, a blend of PTEN-H and IIG20-OH were slot-die coated onto a polyethylene terephthalate (PET) substrate giving uniform thin films suitable for large area device fabrication.
