Abstract The multi-mode/multi-wavelength photoluminescence from a single chromophore can avoid the error of emission properties, which is easily generated from different batches of samples upon mixing of multiple chromophores. Thus, this photoluminescent behavior has better prospects and a wider range of applications. To achieve the multi-mode photoluminescence in a single chromophore, structural modifications from the classic molecules with anti-Kasha rule luminescence properties can be carried out. On the other hand, molecular design with the construction of hydrogen bonding, supramolecular force, and other non-covalent bonds to regulate the singlet-triplet energy level of the chromophores can also be valid. This paper reviewed some representative development and achievements reported in recent years, providing multi-mode luminescence properties by controlling high-low excitation states and singlet-triplet states. Meanwhile, it showed achievements about controlling intensity and ratio of luminescence by using different stimuli. It also made an outlook on applications in function materials about adjustment of multi-mode emissions of single chromophores.
