摘要：

The two series of benzophenone based acid dyes are synthesized using diazotized derivatives of amino benzene sulfonic acid and amino benzoic acid, which were characterized by H-1 NMR, C-13 NMR, CHN analysis and FTIR. They are applied on wool and silk substrate, and their functional properties such as UPF, antibacterial activity and fastness properties are evaluated. The 2,4-dihydroxy benzophenone series showed red shifted absorption and emission compared to 2-hydroxy-4-methoxy benzophenone series. The dyes show excellent UV protection on wool (UPF<40). The dyes and dyed fabrics shows acceptable antibacterial activities for Gram (+) Staphylococcus Aureus (ATCC 6538), Bacillus Subtilis (ATCC 6633) and Gram (-) Klebsiella Pneumonia (ATCC 4352), Salmonella Typhi (ATCC 6539) bacteria. All the fabrics dyed using synthesized dyes can be explored for functional clothing. Frontier Molecular Orbital diagrams obtained and HOMO-LUMO energy band gap was selected to calculate the electrophilicity index values of dyes using Density Functional Theory (DFT).
