“…However, the reaction can immediately cease by the addition of an ammonium molybdate solution. Kireev and Shnyrev have shown the characteristic bands of I 3 − appears at 286 and 350 nm (Figure 5) [ 81 ] A similar observation with our system indicates the generation of hydrogen peroxide during catalysis process. However, it is important to note that the predominant band at 286 nm might be due to the formation of I 3 − only or due to presence of a mixture of I 3 − and benzaldehyde.…”

Visible-light-driven photoreactions using metal complexes as catalysts are currently a research hotspot in terms of the development of environmentally friendly sustainable processes. To develop potential copper-based photocatalysts, a Mannich base ligand, namely, 2,4-dichloro-6-((4-(2-hydroxyethyl) piperazin-1-yl)methyl)phenol (H 2 L), has been synthesized and characterized.Two copper complexes [Cu (HL 1 )] ( 1) and [Cu (HL 2 )] (2) have been obtained from H 2 L, where the ligand undergoes an unprecedented transformation plausibly via oxidation of piperazine ring to ketone, subsequent oxidation of enol and nucleophilic attack of methanol followed by hydrolysis of amide bond, resulting piperazine ring cleavage. Under the irradiation of visible light, these catalysts can oxidize primary alcohols into corresponding aldehydes with very good conversion and high selectivity in the presence of molecular oxygen. The photocatalysts could be recovered almost quantitatively after completion of the catalytic cycle and recycled at least four times without much depreciation of catalytic activity. A plausible mechanistic pathway for alcohol oxidation has been explored through electrospray ionization mass spectrometry (ESI-MS) spectrometric, cyclic voltammetry, UV-vis, and computational study.

“…The different anions do not affect the energy of such electronic transitions as both molar extinction coefficients (ϵ) and absorption energies remain unchanged. The apparent increase of the molar extinction coefficient for the iodide derivatives could be explained by the absorption of the iodide anion that fall in the same spectral region [13] . All compounds display a poor emission in solution with photoluminescence quantum yield (PLQY) <1 % and the emission spectra show no differences in terms of energy profile arising from the naphthalene unit (Figure 9) further corroborating the absence of any ground‐state interaction between the anions and the fluorophore.…”

“…All polymers show characteristic strong signals at 300 nm corresponding either to the organic backbone or to iodine species. [ 32 ] The broadband from 650 nm with a tail extending into the near‐infrared region consistent with the absorbance of neutral PEDOT (650 nm), the polaron (900 nm), and the bipolaron bands (after 1100 nm), which are characteristic of oxidized PEDOT. [ 33,34 ] The intensity ratio of the polaron and bipolaron band of the homopolymer is higher than the copolymers, suggesting that the homopolymer PEDOT‐N has the highest doping level.…”

conducting polymer with the biggest prospects in the emerging field of bioelectronics due to their combination of characteristics (mixed conductivity, stability, transparency, and biocompatibility). [1] In this emerging field, PEDOT is currently being investigated in a number of new applications such as conducting hydrogels, biosensors, organic electrochemical transistors, selective detachment of cells, scaffolds for tissue engineering, electrodes for electrophysiology, implantable electrodes, stimulation of neuronal cells, electronic skin, or pan-bio electronics. [2] The most used PEDOT version is the commercially available aqueous dispersion poly(3,4-ethylen edioxythiophene):poly(styrene sulfonate) (PEDOT: PSS) which is usually processed by casting or spin-coating. However, in order to well connect the two fields of biology and electronics, [3] PEDOT:PSS presents some limitations associated with the low (bio)functionality of the PEDOT polymer and acidity/toxicity of the PSS stabilizer. [4-7] For this reason, in the last few years a number of functional EDOT monomer derivatives has been synthesized including hydroxymethyl, [8] chloromethyl, [9] azidomethyl, [10] carboxylic Poly(3,4-ethylenedioxythiophene) (PEDOT) is the most popular conducting polymer in the emerging field of bioelectronics. Besides its excellent properties and commercial availability, its success is due to the aqueous processability of its anionically stabilized solutions or dispersions. In this work, a water soluble version of PEDOT is shown, which is cationically stabilized. This work reports the chemical oxidative (co)polymerization of EDOT-ammonium derivative leading to PEDOT-N (co)polymers. PEDOT-N shows the typical features of PEDOT such as UV absorbance, bipolaron band, electrical conductivity, electrochemical behavior, and film formation ability. Furthermore, the PEDOT-N films show good biocompatibility in the presence of the human embryonic kidney-293 cell line. The water solubility of PEDOT-N and its cationic nature allows its processability in the form of thin films obtained by the layer-by-layer technique or as conducting hydrogels.
