摘要:
The invention relates to conjugated polymers containing triptycene units. The polymers according to the invention are on the one hand homopolymers comprising a recurring unit containing a triptycenylene radical, and copolymers comprising two or more different recurring units, which may contain a triptycenylene radical or an arylene, heteroarylene, vinylene and ethynylene radical. The polymers according to the invention are employed as electroluminescent materials.
摘要:
In a process for preparing aryl oligoamines, an amine is reacted with an activated aromatic and a base in a temperature range from 0 to 150° C. in the presence of a palladium component and a phosphine ligand. The aryl oligoamines are obtained simply and in good yields.
