1 Carbazole Polymers
Carbazole polymers can be roughly subdivided into
polymers that contain the carbazole group as a pendant
group and those that have the carbazole group in the
backbone. A special variety is a carbazole polymer
with conjugated groups.
The most important class belongsto polymers based
on N-vinylcarbazole (NVK). Carbazole polymers are
reviewed in the literature [1–3].
The interest in poly(N-vinylcarbazole) (PVK) and
related polymers originates because these polymers
are:
1. Photoconductive and have thus found applica-
tions in electrophotography, in
2. Polymeric light-emitting diodes,
3. Organic photorefractive materials, and
4. Photovoltaic ...
