Abstract

The 1,3-Dipolar cycloadditions of terminal diynes with aromatic diazides are used for the generation of nanostructured organic semiconductors by heated atomic force microscope (AFM) cantilever tips. The fabrication is done by nanoscale thermal processing of annealed diazide/dialkyne thin films. The cantilever tip was brought into contact with the film with a load force of ~100 nN and heated. Precision calibration of the cantilever was possible and the tip temperature was near 225 °C. Conjugated polymer form from azide and alkyne precursors under thermal and Cu-catalyzed conditions. It is possible to write crisp nanoscale features into mixed diazide-diyne films after preannealing, using a heated cantilever. The absence of thickness and ripping makes this materials particularly attractive as novel organic semiconductors that can be easily thermally structured.
