Abstract

Fluorous properties represented by water-and-oil repellency are perfluoroalkyl (R-f) compound-specific characteristics, which are widely used for surface coating of glass, electronic devices and textiles for preventing water and grease fouling. According to the stratified dipole-arrays (SDA) theory, the minimum R-f length of (CF2)(7) is theoretically necessary for realizing fluorous properties. Unfortunately, however, production of compounds involving this chemical unit is strictly banned because of concerns of environmental pollution, which is a big dilemma. Here, we show that the fluorous properties can be realized by self-assembled monolayer (SAM) even with a short R-f-containing compound, since the SAM technique makes the best use of the self-aggregation property of the R-f groups, and it readily makes the molecules immobile.
