Lay Summary (English)

Lead
Lay summary
Nanotube research is still a very hot topic with numerous industrial applications, but surprisingly a rational chemical synthesis of nanotubes of given diameter, length and orientation is still lacking.
Based on the experimental finding of graphitic structures during the polymerization of acetylene in presence of an iron hydrogenation catalyst, a template-assisted synthesis of carbon nanotubes was devised. But despite numerous synthetic approaches the selected first generation [0n]-cyclophane template (n = 5 or 6) has not been obtained to date.
The synthesis of two different second-generation template targets was therefore launched, i.e. a rigidified template for bidirectional growth, and a functionalized template for unidirectional growth and sulfur functions for permanent attachment to a suitable electrode surface.
