A polypodal silane compounds are provided for use as a bonded phase and which have embedded hydrophilicity. The compounds have at least two podal branches bonded via an ether linkage or alkoxy group to a hydrophilic group. Each podal branch has a silicon atom which is bonded to each podal branch through a Si—C bond and each of the podal branches is capable of bonding to a siliceous substrate through at least one hydrolyzable functional group capable of being displaced by a Si—O bond. Bonded phases using such compounds and substrates having such compounds bonded to their surface are also described, as well as a method for preparing a bonded phase.
提供了一种用作粘结相的多脚硅烷化合物,具有嵌入的亲水性。这些化合物至少有两个通过醚键或烷氧基与亲水性基团相结合的脚状分支。每个脚状分支都有一个硅原子,通过Si—C键与每个脚状分支结合,每个脚状分支都能够通过至少一个可被Si—O键取代的可水解功能基团与硅质基底结合。描述了使用这种化合物的粘结相和具有这种化合物结合到其表面的基底,以及制备粘结相的方法。
