A method for forming imide silanes containing at least one phenylethynyl moiety, comprising the steps of:

• (a) providing an anhydride containing at least one phenylethynyl moiety;
• (b) providing a substituted silane containing a primary amine group;
• (c) reacting the anhydride with the silane, thereby generating an imide and water;
• and
• (d) removing the water essentially simultaneously with the formation of the imide.
