Abstract

It is a long-standing scientific controversy to achieve anti-Kasha-type multiple emissions by tuning the structures at a molecular level. Although it is known that some conjugated structures have excitation-dependent multiple emissions, no all-benzenoid molecules have yet been reported, the emissions of which originate from different excited states. Herein, we report the design of two symmetry-breaking heterogeneous carbon bisnanohoops that in solution become multiple fluorescent emitters with unusual anti-Kasha characteristics. This phenomenon can be spectroscopically and theoretically explained and will find applications in a wide range of sensing and imaging technologies.
