애플리케이션

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.

A silicon-based nucleophile shown to be reactive in Pd-catalyzed cross-coupling reactions.
