3 Poly(arylene-vinylene)s
Poly(p-phenylenevinylene) (PPV) belongs to the
class of electroluminescent conjugated polymers.
These materials emit light when electric current
is passed through them. For this reason, a sub-
stantial interest emerges in the field of organic
semiconductors.
A lot of papers have appeared dealing with this
topic, often focused on the physical aspects, however
there are reviews dealing with chemical aspects, such
as synthesis of these polymeric types [1].
To the family of π-conjugated polymers, besides
PPV, other types belong, such as poly(p-pyridyl viny-
lene), poly(p-phenylene ethynylene), poly(p-thienyl
vinylene), poly(3-hexylthiophene), ...
