Despite this extensively explored chemical space, there is still room to discover core-substituted NDIs with fundamentally new properties: NDIs with cyclic trisulfides (i.e., trisulfanes) in their core absåorb at 668?nm, emit at 801?nm, and contract into disulfides (i.e., dithietes) upon irradiation at ID - 1655 ER -
