In the present study, a new (E)-rich-enyne pi-conjugated polymer containing a carbazole was designed and synthesized. Two different synthesis methods of poly[N-(2-ethylhexyl)-3,6-carbazolyleneethynylene-(E)-vinylene] (PCZEV) have been prepared from 3,6-diethynyl-9(2-ethylhexyl)carbazole by using the palladium-carbene-catalyzed reaction and/or by using the organolanthanide-catalyzed reaction leading to well-defined polymer, and their general properties were studied. Compared to poly[N-(2-ethylhexyl)-3,6-carbazolyleneethynylene] (PCE), the UV-Vis absorption and photoluminescence of the PCZEV was red-shifted, which indicates the extension of conjugation length.
