Diarylmethane dye
WebThe dye molecules characterized with: satisfactory water solubility, significant photostability at adequate pH, high kinetics rate of interaction with proteins. Besides, the dye did not display exclusive sensitivity to the chelator molecules, the detergent agents and the inhibitor ingredients [ 78 ]. WebDiphenylmethane is a common skeleton in organic chemistry. The diphenylmethyl group is also known as benzhydryl . Synthesis [ edit] It is prepared by the Friedel–Crafts alkylation of benzyl chloride with benzene in the presence of a Lewis acid such as aluminium chloride: [2] C 6 H 5 CH 2 Cl + C 6 H 6 → (C 6 H 5) 2 CH 2 + HCl
