| Hazard Information | Back Directory | [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.
