Synthesis of Novel Fluoroalkylated Oligomers Containing Phosphinico Segments:  A New Approach to Functional Materials Possessing Anti-HIV 1 Activity

Synthesis and properties of novel fluoroalkyl end-capped oligomers containing phosphorus segments

“…In preliminary communications, we found that novel fluoroalkyl end-capped oligomers containing pendant phosphoric acid groups are prepared by use of fluoroalkanoyl peroxides and these fluorinated oligomers possess a selective anti-HIV 1 activity in vitro. 8 We now give a full account of the synthesis and properties of fluoroalkyl endcapped oligomers containing phosphorus segments.…”

Application of Ionic Liquid as Surface Modifier :

“…On the other hand, fluoroalkyl end-capped oligomers are attractive functional materials because they exhibit a variety of unique properties such as high solubility, surface active properties, biological activities, and nanometer size-controlled selfassembled molecular aggregates which cannot be achieved by the corresponding non-fluorinated and randomly fluoroalkylated ones [21][22][23][24] . Especially, we have already reported that fluoroalkyl end-capped oligomers are potential surface modifiers for not only inorganic materials such as glasses, stainless steel and aluminum plate but also traditional organic polymers such as polystyrene and poly methyl methacrylate to exhibit a good oleophobicity imparted by fluorocarbon [25][26][27][28] . Thus, it is strongly expected that the introduction of hydrophilic ILqds into fluoroalkyl end-capped oligomers should exhibit a switchable wettability between the oleophobicity imparted by fluorocarbon and hydrophilicity derived from ILqds through the flip-flop motion between fluoroalkyl groups and ILqds segments in fluorinated oligomers adapting to the surface environmental changes.…”
