Highly efficient light-emitting diodes based on an organic-soluble poly (p-phenylenevinylene) derivative carrying both the hole-transporting carbazole moiety and the 2-ethylhexyloxy group

Synthesis and characterization of conjugated polymers containing a carbazole moiety

“…Additionally, electroluminescent polymers with a carbazole moiety have been widely investigated due to their excellent hole-transporting performance and thermal stability. [16][17][18][19][20][21] In order to get some more systematic knowledge, another two series of conjugated polymers with a carbazole moiety, which have a similar chemical structure to two above series of electroluminescent polymers, were synthesized by Knovenagel and Wittig condensations in this paper. The chemical structure, thermogravimetric, photophysical, and electrochemical properties of the polymers were characterized and discussed in detail.…”
