Spectroscopy of Dyes in Polymer Matrices: Dual Fluorescence of a [p-(Dialkylamino)benzylidene]malononitrile Dye in Poly(viny1 acetate) Matrices K. Y. Law and R. 0. Loutfy* Xerox Research Centre of Canada, 2480 Dunwin Drive, Mississauga, Ontario L5L 1J9,Canada. Received August 12,1980 ABSTRACT The dynamic behavior of a dye-in-polymer was revealed by electronic spectroscopy. Absorption, emission, and polarization spectra of [p-(dialkylamino)benylidene]malononitrile1 in poly(viny1acetate) (PVAc) showed that the dye exists in monomeric form only a t very low concentrations (
