Spin doctor : The polymacrocyclic oligoarylamine in the picture serves as a multispin source owing to its multi‐electron redox activity. As a result of its pseudobeltane structure and para ‐phenylenediamine bridges, the radical cation can convert between two sideslipped structures with a windshield‐wiper‐like motion. In contrast, the tetraazacyclophane units are rigid components in the polymacrocycle.
