ABSTRACT A new series of benzidine‐based bisazo metal complexes were synthesized, characterized, and applied for polyester fabric dyeing. The parent dye was prepared by diazotizing benzidine coupling it with acetylacetone. This then complexed Fe (III), Cr Cu (II), Mn Ni (II) ions to produce five complexes. structures the synthesized compounds confirmed using spectroscopic techniques, including FT‐IR, NMR, TGA, elemental analysis. Enhanced thermal stability relative demonstrated Moreover, when fabrics, superior performance observed through colorimetric analysis fastness testing. highest color strength ( K / S = 12.5) exhibited iron complex. Excellent properties (ratings 4–5 or 5) achieved washing, perspiration, light fastness. Significant variations in characteristics between revealed CIE Lab electronic reactivity investigated DFT calculations.

Extractives, which naturally evolve as fundamental defense mechanisms in wood against environmental stresses, hold an essential place the field of conservation science. Despite their low content woody substrates, extractives are chemically complex and can be extracted accurately by solvents with different polarities, covering key components such aliphatic, terpenoid, phenolic compounds. The application solvent extraction allows for effective recovery these extracts from forestry waste, thereby creating new opportunities reuse modification enhancing economic value potential applications waste. In industry, not only act efficient preservatives photo-stabilizers, significantly improving decay resistance photodegradation wood, but also serve ideal dyes fast-growing due to abundant natural colors, lend product a distinct aesthetic appeal. aim this paper is provide comprehensive review origin distribution characteristics examine impact selection on efficiency. At same time, mechanism slowing down deeply analyzed. addition, specific examples presented illustrate wide utilization industry. This intended references research practice related fields.
