General description

Tetratetracontane is a long chain alkane. It is the main constituents of essential oils from Euphorbia macroclada. Coadsorption of tetratetracontane and [Na(H2O)P5W30O110] results in single, isolated surfactant-encapsulated clusters on a buffer layer of tetratetracontane, which was determined by scanning tunneling microscopy. Thermooxidative degradation of tetratetracontane has been reported.

Application

Tetratetracontane may be used in a passivation layer in copper-phthalocyanine field-effect transistors for improving the charge carrier mobility. It may be used to modify the quasi two-dimensional surface electron system on Au(111), which was investigated by angle-resolved photoemission spectroscopy.

We report on the self-assembly of several surfactant-encapsulated clusters (SECs) on the basal plane of graphite consisting of the doughnut-shaped tungstophosphate anion [Na(H2O)P5W30O110] covered by a hydrophobic shell of surfactants. Well-ordered rodlike structures are observed using scanning force microscopy. No
