A. Benjelloun et al., AMPHIPHILIC COPOLYMERS IN AQUEOUS-MEDIUM - CHARACTERIZATION OF THE STRUCTURE OF THE HYDROPHOBIC MICRODOMAINS, Macromolecular symposia, 127, 1998, pp. 165-171
The behaviour of new cationic amphiphilic copolymers derived from 3-vi
nylpyridine was studied in aqueous medium. The formation of hydrophobi
c microdomains was evidenced by fluorescence spectroscopy using a mole
cular rotor as a fluorescent probe and their structure was visualized
by cryo-transmission electron microscopy (Cryo-TEM). The parameters (s
hape and size) obtained from Cryo-TEM were discussed in relation to th
e copolymers composition and to the local viscosity defined by the rot
or fluorescence quantum yield.
