Metallic species such as iron, nickel and cobalt are known to catalyze the
growth of CNTs in the CVD process [168-170]. Because of the ready ther-
mal curability of the
hb
-PYs, spin-coated films of organometallic polymers
81
and
82
are expected to restrict the agglomeration of the metallic nanoclusters
in the CVD process and hence to provide nanoscopic catalyst seeds for the
