Sh. Huttenhain et al., FLUORESCENCE OF 8-(PHENYLAMINO)-1-NAPHTHALENE-AMMONIUMSULFONATE IN SOLVENTS OF DIFFERENT POLARITY, Zeitschrift fur Naturforschung. A, A journal of physical sciences, 49(11), 1994, pp. 1087-1090
The solvatochromic fluorescence properties of 8-(phenylamino)-1-naphth
alene-ammoniumsulfonate (1) were investigated in 22 pure solvents of r
ising polarity. The measurements of both Stokes' shifts and intensitie
s discriminated between protic and aprotic solvents. Fairly good linea
r correlation plots of the dependence could be obtained on neglection
of the values of tert.-butanol, DMF and DMSO.
