as new templates for the assembly of unprecedented azo-functionalized hydrogen-bond-assembled [2]rotaxanes. Moreover, these binding sites can be reversibly and efficiently interconverted with their hydrazo forms through a hydrogenation-dehydrogenation strategy of the nitrogen-nitrogen bond. This novel chemically switchable control element has been implemented in stimuli-responsive molecular shuttles

Well-defined structural changes of molecular units that can be triggered by light are crucial for the development of photoactive functional materials. Herein, we report on a novel switch that has azodicarboxamide as its photo-triggerable element. Time-resolved UV-pump/IR probe spectroscopy in combination with quantum-chemical calculations shows that the azodicarboxamide functionality, in contrast to
