Process for the synthesis of aryl- or heteroarylamine boronic acid derivatives

摘要

Conjugated copolymer (A) comprises at least one block-like structure with specific properties, where these structures are linked through (partially) statistical copolymer segments (X). Conjugated copolymer (A) comprises at least one block-like structure with at least the following properties: (a) charge-transport block, for transport of holes or electrons; (b) a charge-injection block (for positive or negative charges); (c) an emitting block; (d) a block that facilitates transition of singlet to triplet excitons; and (e) a polymeric base scaffold block. The new feature is that these block structures are linked through (partially) statistical segments (X). Independent claims are also included for the following: (1) blends (A1) containing one or more (A); (2) solutions containing one or more (A) or (A1) in one or more solvents; (3) method for preparing (hetero)arylamino-boronic acid derivatives (I) by Hartwig-Buchwald coupling; and (4) electronic components comprising one or more active layers, at least one of which contains at least one (A) or (A1).
