Carbohydrates, azido-containing groups

In addition, bifunctionalized carbohydrate derivatives containing simultaneously one azido and alkyne groups have been intermoleculary reacted, affording cyclic carbohydrate-containing molecule of interest that also possess more that one triazole ring in their structures. 

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.
