alkoxysilaner
Alkoxysilanes are a family of organosilicon compounds in which one or more alkoxy groups (–OR) are bonded to a silicon atom. They can be described by general formulas such as Si(OR)4 (tetraalkoxysilanes) and RSi(OR)3 (trialkoxysilanes), with partial substitutions yielding dialkoxysilanes and related species. A defining feature is their susceptibility to hydrolysis: in the presence of water, Si–OR bonds are cleaved to form silanols (Si–OH), which then condense to form siloxane (Si–O–Si) linkages. This reactivity underpins their broad use in materials science.
Common examples include tetraethoxysilane (TEOS), tetramethoxysilane (TMOS), methyltrimethoxysilane (MTMS), vinyltrimethoxysilane (VTMS), and 3-aminopropyltriethoxysilane (APTES). Such compounds
Applications of alkoxysilanes span sol-gel processing to produce silica networks, surface modification of glass and ceramics,
Synthesis and handling are generally moisture-controlled. Many alkoxysilanes are prepared by alcoholysis of silicon halides (for
