4 4'-BIS(TRIETHOXYSILYL)-1 1'-BIPHENYL Usage And Synthesis

Uses

suzuki reaction

Uses

4,4′-Bis(triethoxysilyl)-1,1′-biphenyl (BTESB) can be used as an indicator to determine the chirality of helical silica nanotubes. BTESB can also be utilized as a precursor to prepare:

Helical 4, 4′-biphenylene-silica nanotubes and nanoribbons using 3-aminopropyltrimethoxysilane as a co-structure-directing agent.
Biphenyl-bridged alkoxysilane-based crosslinked polyalkoxysilane by condensation with linear aliphatic diols.
Biphenylene-bridged silsesquioxane thin films by the sol-gel method.
