Hj. Verhey et al., DETECTION OF NANOSCALE EVENTS IN DISPERSED POLYMER PARTICLES CONTAINING A CHARGE-TRANSFER FLUORESCENCE PROBE, Journal of polymer science. Part A, Polymer chemistry, 33(3), 1995, pp. 399-405
A probe molecule, which shows an unusually large change in fluorescent
properties in response to changes in its environment, was introduced
into a monodisperse polystyrene latex. Upon addition of low-molecular-
weight compounds, the ensuing swelling process of the latex could be f
ollowed via the changes in the fluorescence spectrum of the probe mole
cule. Polymerization reactions of monomers, introduced into the partic
les, could also be monitored by means of this approach. Using glycidyl
methacrylate as the monomer led to the formation of particles in which
two distinctly different surroundings could be detected after such a
polymerization. (C) 1995 John Wiley and Sons, Inc.
