Azides containing silicon

A new group of azides containing silicon of general formulae... 

Fig. 12. Generation of phenyl silaisocyanide, the first molecule reported to contain a triple bonded, singly coordinated silicon atom, by controlled explosion of triazido(phenyl)silane and its PE-spectroscopic identification together with the ionization fingerprints of N2 (black), a most advantageous leaving molecule. Triazido(phenyl)silane is prepared Ifom trichloro(phenyl)silane by azide exchange with trimethylsilyl azide in the presenee of AICI3 [11].

Azido photochemistry was frequently used to introduce functional groups onto polymeric substrates. It is also the main so-called grafting-to technique usually used to efficiently modify or functionalize surfaces [HAR 91, THO 98, ZIA 99]. This method was employed to covalently graft carbohydrates [KNA 01] or polysaccharides [BAR 01, BHA 08] containing azide groups to polymer substrates and was successfully used to modify a wide range of other substrates such as glass, tin oxide, silicon and aluminum.
