| Abstract: | It has been stated by 1H NMR and UV spectrophotometry that 1-(4-tert-butil-phenoxy)-2-cetylamino-9,10-anthraquinone photoisomerizes to 9-(4-tert-butylphenoxy)-2-cetylamino-1,10-anthraquinon with quantum yield ? = 0.4 ±0.1 under light excitation in the absorption band region in the UV/visible spectrum range with the maximum λ = 441 nm. |
