## Abstract A series of dicarbazolyl derivatives bridged by various aromatic spacers and decorated with peripheral diarylamines were synthesized using Ullmann and Pdโcatalyzed CโN coupling procedures. These derivatives emit blue light in solution. In general, they possess high glassโtransition temp

## Abstract New carbazoleโbased copolymers, which contain various concentrations of 9โalkylโ3,6โcarbazole fragments in the main chain connected via alkylene spacers, have been synthesized by Ni(0)โcatalyzed Yamamotoโtype arylโaryl coupling reactions. Full characterization of the copolymer structure
The performance of organic light-emitting devices (OLEDs) is strongly influenced by the electronic properties of the employed materials. In order to determine the effect of these materials' parameters, several different hole-transporting 1,3,5-tris(4-diphenylaminophenyl)benzenes (TDAPBs) were synthe
