A. Kawski et al., UNUSUAL ABSORPTION AND FLUORESCENCE PROPERTIES OF P-SUBSTITUTED STILBENES IN POLY(VINYL ALCOHOL) FILMS, Zeitschrift fur Naturforschung. A, A journal of physical sciences, 50(12), 1995, pp. 1170-1174
The behaviour of absorbance, fluorescence and emission anisotropy of l
inear molecules with one double bond, i.e. 4-amino-4'-nitrostilbene (A
NS), 4-dimethylamino-4'-nitrostilbene (DNS) and 4,4'diphenylstilbene (
DPS), was examined in poly(vinyl alcohol) (PVA) films at different tem
peratures (293-423 K). The unusual behaviour of absorption and fluores
cence properties of the molecules investigated, similar to those of li
near polyenes in PVA, was, however, less pronounced.
