醌类化合物是一类具有独特生物活性和光物理性质的重要化合物.以吲哚萘醌和磺酰基肼为底物,经历碘化亚铜/过氧化叔丁醇介导的氧化自由基历程,简单、高效地以22%～67%的收率获得了8 种取代的磺酰基醌类化合物(6a～6h),产物结构经过1 H NMR,13 C NMR和HR-MS(ESI)表征.初步探究了化合物6a～6h的光物理性质,结果表明:可以通过不同位置的取代基的变换来调节化合物的最大紫外吸收波长和荧光发射强度.
Synthesis and Photophysical Properties of Novel Sulfonyl Indolynaphthoquinones
Quinones are important compounds for the unique biological activity and photophysical prop-erties.Here,eight substituted sulfonyl quinones(6a～6h)were synthesized in 22%～67%yields through cuprous iodide/tert-butyl peroxide mediated oxidation radical process with the use of indo-linaphthoquinone and sulfonyl hydrazine,and the product structure is characterized by 1 H NMR,13 C NMR and MS(ESI).The photophysical properties of compounds6a～6h were investigated and the results showed the maximum UV absorption wavelength and fluorescence emission intensity of the com-pound can be adjusted by changing the substituents at different positions.
