1,1,3,3,5,5-hexaethoxy-1,3,5-trisilacyclohexane Chemical Properties,Usage,Production

Uses

1,1,3,3,5,5-hexaethoxy-1,3,5-trisilacyclohexane is a known organosilane building block that can be used to synthesize PMO thin films^[1] and EMA-2 materials^[2]. PMO thin films can be used as one of the candidate materials for ultra-low-k dielectrics in microelectronic devices. Studies have shown that this building block is stable in acidic gels, but gradually opens when the gelation temperature and time exceed the "standard" conditions used for alkaline gels.
