  Fluoroalkyl silanes are a class of compounds useful for various industrial purposes. For example, fluoroalkyl silanes which have hydrolysable groups (called hydrolysable fluoroalkyl silanes), are compounds useful as surface treatment agents which provide durable hydrophobic and oleophobic coatings. In general, hydrolysable fluoroalkyl silanes can be represented with the following formula: (RO—) 3 Si—R T wherein R is H or an alkyl; and R T is a monovalent organic compound terminated by a perfluoroalkyl group. When used to coat a surface, the (RO—) 3 moiety reacts (via hydrolysis) with various chemical groups of the surface (e.g., hydroxyl, amine, or other reactive groups) thereby bonding the fluoroalkyl silane to the surface The R T moiety comprises a divalent organic linking group which links the silicon atom to a terminal group rich in fluorine atoms whose unique electronic properties impart desirable hydrophobic and oleophobic properties in a surface coating. Modification of the R T moiety is useful in the engineering of fluoroalkyl silanes. The present invention provides for fluoroalkyl silanes having R T moieties which have not been heretofore considered.

  氟烷基硅烷是一类在各种工业用途中有用的化合物。例如，具有可水解基团（称为可水解氟烷基硅烷）的氟烷基硅烷是作为表面处理剂有用的化合物，可以提供耐久的疏水和疏油涂层。通常，可水解氟烷基硅烷可以用以下公式表示：(RO—)₃Si—RT，其中R为H或烷基；RT是以全氟烷基基团为末端的一价有机化合物。当用于涂覆表面时，(RO—)₃基团通过水解与表面的各种化学基团（如羟基、胺基或其他反应性基团）发生反应，从而将氟烷基硅烷与表面结合。RT基团包括一种双价有机连接基团，将硅原子与富含氟原子的末端基团连接起来，其独特的电子性质赋予涂层中理想的疏水和疏油性能。对RT基团的修改对于工程氟烷基硅烷是有用的。本发明提供了具有未被考虑过的RT基团的氟烷基硅烷。
