Polythiophenes with alcohol, tosylate, azide, ethynylene, carboxylic acid, and amine end groups were prepared by a combination of functionalized nickel initiators and postpolymerization reactions. The azide and ethynylene polymers were subsequently used in a click reaction to produce a conjugated block copolymer. Finally, a conjugated triblock-copolymer was synthesized by means of a chain growth polymerization initiated by a binuclear nickel initiator.

The present invention relates to a process for the preparation of 1,4,5- trisubstituted triazoles and 3,4,5-trisubstituted triazoles according to Formulas (Ia) and 5 (Ib), and mesomers and tautomers thereof, wherein a compound according to Formula (II) or Formula (III): is reacted with a compound according to Formula (IV). The process is very useful for the selective and site-specific addition of azide compounds to optionally activated alkynes to form 1,4,5-trisubstuted triazoles and mesomers and tautomers thereof and the application of this process to the covalent functionalisation of biomolecules.
