The entanglement of states is a fascinating result of quantum physics. In the singlet fission process, a pair of chromophores in the S 1 S 0 state evolves into the spin‐entangled T 1 T 1 state. While most studies on singlet fission have been restricted to alternated hydrocarbons, the potential of diradicaloids as singlet fission chromophores has remained largely unexplored. In their Research Article on page 7906, M. M. Hansmann, D. Munz, D. M. Guldi et al. present a new family of carbene‐derived diradicaloids undergoing this photophysical process. The entangled T 1 T 1 state is depicted as two climbers holding hands.
