“…It is important to mention that the values obtained, reported in Table 4 , are lower than for some OS films such as; the PVOH (polyvinyl alcohol) film embedded with Bi‐nanoparticles (0.604 eV) [51] or the hydroxypropyl methyl cellulose film (0.556–0.874 eV) [55] and are similar to those obtained, for example, by Zoromba et al. [56] for o‐phenylene diamine dihydrochloride film (0.387 eV). This is an indication that uranyl(VI) films present E U in the range of those obtained for OS films, and even with the presence of defects that can act as traps that have the potential to transport charge between their HOMO and their LUMO.…”

“…The width of E U depends on the position of nitrogen in the pyridine, apparently, the N in 4‐position generates the least number of defects during the deposit of the complex.

In this work, it is proposed the development of organic semiconductors (OS) based on uranyl(VI) complexes. The above by means of the synthesis and the characterization of the complexes by Infrared spectroscopy, Nuclear magnetic resonance spectroscopy, mass spectrometry, and X‐ray diffraction. Films of these complexes were deposited and subsequently, topographic and structural characterization was carried out by Scanning Electron Microscopy, X‐ray diffraction, and Atomic Force Microscopy. Additionally, the nanomechanical evaluation was performed to know the stiffness of uranyl films using their modulus of elasticity. Also, the optical characterization took place in the devices and their bandgap value ranges between 2.40 and 2.93 eV being the minor for the film of the uranyl complex with the N on pyridine in position 4 (2 c). Finally, the electrical behavior of the uranyl(VI) films was evaluated, and important differences were obtained: the uranyl complex with the N on pyridine in position 2 (2 a) film is not influenced by changes in lighting and its current density is in the order of 10−3 A/cm2. The film with uranyl complex with the N on pyridine in position 3 (2 b) and 2 c presents a greater current flow under lighting conditions and two orders of magnitude larger than in film 2 a. In these films 2 b and 2 c, ohmic behavior occurs at low voltages, while at high voltages the charge transport changes to space‐charge limited current behavior.

Keto-bromothymol blue [BTB] keto was quantitatively prepared by potassium permanganate oxidation of bromothymol blue in an alkaline medium at pH > 12. When reacting with dinitrophenyl hydrazine and hydroxylamine, the obtained keto derivatives were characterized by FTIR, TDDFT-DFDT computations, and optical properties. The resulting compounds were found to have a high chelation affinity with most of the dinitrophenyl hydrazine and hydroxylamine forming stable bromothymol blue coordination compounds. The commodity has low cost and high performance and is used in food, drink, or other non-food applications such as pharmaceuticals. Furthermore, keto-bromothymol blue dye is applied for commercial, psychological, and functional purposes in dietary supplements and pharmaceutical products. The characterization of the [BTB] keto , [KBTB-DNPH], and [KBTB-HA] thin films was carried out by some practices comprising UV-Vis, and thin films were fabricated by a spin coating. The direct energies were 2.452 eV, 1.991 and 2.927 eV for [BTB] keto , [KBTB-DNPH] and [KBTB-HA] thin films, respectively. The ΔE Opt g values were computed depend on the difference among HOMO and LUMO using the DMol 3 method in TDDFT-DFT computations. The optical dispersion of the thin films was confirmed in terms of WD model. DFT/DMol 3 and Gaussian 09w/DFT computations were used for the optimization of the keto-derivatives as gaseous state molecule matrices. The Gaussian program is in good agreement with the experimental analysis for synthetic IR, MEP, and UV-Vis optical properties. In addition, the optoelectrical parameters have been calculated for the film, namely n(λ), k(λ), dielectric constant, and optical conductivity. CASTEP simulated values are consistent with the experimental values for optical parameters of dye derivative thin films. The fabricated thin films can be used as a candidate material for optoelectronic devices and solar cells.
