Norbornadiene-based photoswitches with exceptional combination of solar

Norbornadiene-quadricyclane (NBD-QC) photo-switches are candidates for applications in solar thermal energy storage. Functionally they rely on an intramolecular [2+2] cycloaddition reaction, which couples the S0 landscape on the NBD side to the S1 landscape on the QC side of the reaction and vice-versa. This commonly results in an unfavourable
