However, their susceptibility to corrosion in aggressive environments limits the application reliability. Although chromate-based passivation is highly effective, it is harmful to both the environment and human health. This review systematically evaluates recent advances in green copper corrosion inhibitors from experimental and theoretical perspectives. The copper corrosion inhibitors are categorized into inorganic (e.g. molybdates, phosphates, tungstates, rare earth, carbon quantum dots), organic (e.g. nitrogen-containing heterocyclic, sulfur-containing and novel structure compounds, natural plant extracts, expired pharmaceuticals) and organic-inorganic composite (e.g. graphene, SiO<sub>2</sub> composites, nanocontainers) systems. Based on the analysis of experimental research results, it is found that they demonstrate enhanced protection through optimized molecular structures, synergistic formulations, multilayer films, and nanocontainer-enabled controlled release. Surface hydrophobic modification further improves performance under harsh conditions. Theoretically, density functional theory, molecular dynamics and adsorption isotherm model analysis reveal that high-efficiency inhibitors typically exhibit energy gaps of 4.00-6.00 <em>eV</em>, dipole moments of 2.00-6.00 <em>Debye</em>, and adsorb parallel to the Cu surface via heteroatoms (N, O, S etc.) with adsorption energies of -800 to -100 <em>kJ/mol</em>. Adsorption generally follows the Langmuir model, combining physical and chemical mechanisms with a dominance of chemisorption. These insights establish structure-performance relationships and guide the rational design of green, high-efficiency inhibitors.

These adsorbents were thoroughly characterized by FT-IR, Raman, XRD, TGA, and SEM analyses. Batch adsorption experiments were conducted to evaluate the effects of pH, contact time, initial Cr concentration, adsorbent dosage, and temperature on the adsorption of Cr ions by GO-CAA, GO-CPA, and GO-CBA adsorbents under various conditions. Maximum Cr removal was observed at pH 1, with GO-CBA showing superior adsorption efficiency (98.7% at 25 mg/L, 0.01 g dosage), followed by GO-CPA (98.0%) and GO-CAA (96.3%). At 50 mg/L, complete Cr removal (100%) was achieved within 4 h using 0.015 g of each adsorbent. The adsorption process followed pseudo-second order kinetics, indicating chemisorption, and thermodynamic analysis confirmed the process as spontaneous and endothermic. The adsorption capacity values fitted well with the Langmuir isotherm, and the experimentally determined maximum capacities were 79.43 mg/g (GO-CBA), 71.02 mg/g (GO-CPA), and 50.58 mg/g (GO-CAA), closely matching the calculated values. GO-CBA exhibited the highest enthalpy and entropy changes, suggesting stronger interaction with Cr. Reusability tests demonstrated excellent regeneration performance and structural stability. Additionally, GO-CAA was effective in removing Cr(III) at pH 3.

To contribute to better understanding of the effect of lateral substitution on self-assembling and photoactive behaviour, several new azobenzene based rod-like materials with different lateral substituents (bromine/chlorine atoms, methyl group) placed close to the azobenzene moiety are designed. The mesomorphic behaviour was established using polarized-light optical microscopy, differential scanning calorimetry, and X-ray diffraction techniques. Independently on the type of lateral substitution, all materials exhibit the self-assembling behaviour; specifically, they form cholesteric and smectic phases; but the substituents play quite important role on the type of mesophase and its temperature range. The photo-isomerization process, specifically the conversion of the <em>E-Z</em> isomers, was studied in toluene solution by high performance liquid chromatography; the kinetics of the photo-isomerisation was established under UV-light (366 nm) irradiation.
