A borate ester network Langmuir-Blodgett film of 1,3,5-benzenetriol monohexadecyl ether

A two-dimensional borate network of an amphiphilic phenol has been produced through the Langmuir-Blodgett (LB) technique. An amphiphilic phenol, 1,3,5 -benzenetriol monohexadecyl ether (C16 1,3,5-BT) was synthesized by the rea ction of phloroglucinol dihydrate (1,3,5-benzenetriol) with 1-iodohexadecan e. Monolayers of C16-1,3,5-BT were spread on the 1% aqueous boric acid subp hases with various pH. The molecular structure of the LB film was determine d by the FT-IR and XPS. The mechanical stability of the network film was in directly evaluated by the SEM observation of the film morphology covered ov er the porous substrate.
