Stable Quadruple Helical Tetraradicaloid with Thermally Induced Intramolecular Magnetic Switching

We report an air-stable tetraradicaloid based on a rarely explored perylenequinonoid (PQ) core, namely, tetrabenzo-annulated tetracyclopenta[b,e,k,n]perylene (TBCP), which has a quadruple helical s...
