H. Sawada et al., DIRECT AROMATIC FLUOROALKYLATIONS OF POLY(P-PHENYLENE) WITH FLUOROALKANOYL PEROXIDES, AN APPROACH TO HIGHLY SOLUBLE FLUORINATED CONDUCTING POLYMERS, Journal of fluorine chemistry, 82(1), 1997, pp. 51-54
Direct aromatic fluoroalkylations of poly(p-phenylene) (PPP) using flu
oroalkanoyl peroxides were found to give excellent to moderate fluoroa
lkylated ratios even in heterogeneous systems. The fluoroalkylated pro
ducts (PPP-R-F) were shown to possess dramatically higher solubilities
than parent PPP, and the improvement in the solubility enabled measur
ements of the molecular weights of PPP-R-F to be made by gel permeatio
n chromatography analyses, Perfluoropropylated PPP formed a monomolecu
lar film at the air-water interface. This deposited film was found to
conduct electricity, and its electric conductivity was comparable with
the conductivities of similar films formed from other compounds of po
tential interest in this field. (C) 1997 Elsevier Science S.A. All rig
