Octadecanephosphonic acid

Stearic (octadecanoic) acid, CH3 (CH2)l6COOH Octadecanephosphonic acid, CH3(CH2)i7P03H2 Octadecanephosphoric acid, CFl3(CH2)i70PO(OH)2 Dodecanephosphoric acid, OH—or CH3(CH2)iiOPO(OH)2... 

Whitesides and coworkers [435] have examined the preparation and properties of SAMs obtained by adsorption of long-chain alkanoic acids and alkanephosphonic acids as well as alkanehydroxamic acids onto metal oxide surfaces such as Ti02 and Zr02. Monolayers of octadecanoic acid and octadecanephosphonic acid were formed from solutions in either isooctane or ethanol with concentrations of 1 mM in... 

Fadeev and coworkers [439] have reported the comparative study of the reactions of octadecanesilanes with different headgroups and of octadecanephosphonic acid for the surface modification of Ti02... 

Aluminum is commonly used as a metallization layer in the microelectronics industry. Whitesides and coworkers [471] showed that octadecanephosphonic acid can be patterned on AI2O3/AI by pCP and that patterned structures are electrically similar to samples prepared by conventional photohthography and lift-off. 

The patterned structures resulting from etching are continuous and electrically conductive within each pattern, and separated patterns are electrically isolated. Using pCP, Schottky diodes of aluminum have been prepared on p-type Si(lOO). Octadecanephosphonic acids are air stable compounds that are known to form stable, ordered monolayers on metal oxide surfaces [298,435]. SAMs on the native oxides of aluminum [435, 472, 473] and copper or iron [435, 473] have been formed from alkanephosphonic acids.
