Abstract
The effect of hydrogen-bonding additives on the surface modification of a h
ydrogen-bonded organic pigment is studied using absorption and fluorescence
spectroscopy. Evidence for surface dissolution that occurs during the mixi
ng of solids is presented. The spectral signatures of monomers and hydrogen
-bonded aggregates of the pigment that are present on the surface of crysta
llites of the pigment are quite distinct, as revealed by fluorescence excit
ation and emission spectra. (C) 1999 Academic Press.
