New silanes and their use for the silanization of dielectric materials.

摘要

The present invention concerns a NEW SILANE AS WELL AS PROCESS FOR THEIR USE MATERIAL SILANIZATION dielectrics and ANCHOR FOR BIOLOGICAL ACTIVE COMPOUNDS. Silanes have the formula GENERAL I where R1 R2 R3 HIRE, alkoxy or halogen, wherein at least one of these radicals are OR alkoxy- or halogen and SONDE Y represents an alkylene chain [UORALQUILENO [-] N = 1 are characterized such that the x MEAN an epoxide, an anhydride of a dicarboxylic acid with 4 out of C, an isothiocyanate, UN fLUORIDE aCID arylcarboxylic chloride or arylsulfonic acid, provided THAT IF THE GROUP X is an epoxide, at least one of the radicals R1 R2 R3 is halogen. NEW silanes according to the invention have the following advantages: the x silane reagents are stable to hydrolysis but sufficiently ACTIVE, SO IT IS ACHIEVED immobilizing a molecule recognized Biologically, without continuing OTHER STEPS TO ACTIVATE LAYER silane. Silanes are characterized by DIRECT COATING MATERIALS SPECIAL dielectrics dielectrics ONDA DRIVERS ARE MADE UP WITH PREFERENCE ZrO2, HfO2, Ta2O5, SiO2, Al2O3 or TiO2. Silanes CAN BE APPLIED FROM BOTH AS A SOLUTION FROM GAS PHASE ON SURFACES OF MATERIALS dielectrics. Hydrolysis STABILITY reactive groups results in an improved storage stability LAYERS Silane and allows direct use in aqueous medium.
