The Chemist’s Way to New Carbon Materials:
nano- and Surface Confinement of
Polyphenylenes

Carbonaceous materials and, in particular, discrete
carbon nanoparticles are a matter of great fundamental
and practical interest. While methods of carbon
nanoparticle formation such as chemical vapor
deposition have recently shown enormous strength,
there is still a need for more selective, “milder” methods
which might also provide access to hitherto unprecedented
carbon nanoparticles. Toward that end
we are introducing “precursor controlled pyrolysis”
and “templated pyrolysis” in confining geometries.
Thereby polyphenylene dendrimers and nanographenes
as well as their organometal derivatives
are important molecular building blocks for complex
self-assembly processes, but also serve as unique
precursors for the pyrolytic formation of novel carbon
nanoparticles.
