Abstract The solvatochromic fluorescence properties of 8-(phenylamino)-1-naphthalene-ammoniumsulfonate (1) were investigated in 22 pure solvents of rising polarity. The measurements of both Stokes' shifts and intensities discriminated between protic and aprotic solvents. Fairly good linear correlation plots of the dependence could be obtained on neglection of the values of tert.-butanol, DMF and DMSO.

8-(苯氨基)-1-萘-磺酸铵在不同极性溶剂中的荧光

摘要 研究了8-(苯基氨基)-1-萘-磺酸铵(1)在22种极性上升的纯溶剂中的溶剂化显色荧光性质。斯托克斯位移和强度的测量区分质子溶剂和非质子溶剂。忽略叔丁醇、DMF 和 DMSO 的值​​，可以获得相当好的相关性线性相关图。
