Pure organic luminescent supramolecular materials with either phosphorescence or fluorescence emission have become a hot research topic due to their low toxity, facile preparation and wide applications. In recent years, our group has designed several novel luminescent macromolecules, achieving tunable multi-color emission. For the construction of phosphorescent materials, heavy atoms such as bromine and iodine as well as other hetroatoms with lone pair electrons like oxygen were employed to facilitate the intersystem crossing (ISC) process of the luminophores while rigid environments were provided via host-guest interactions and polymerization to restrict molecular motions, which results in reduced nonradiative decay. Moreover, noncovalent interactions are stimuli responsive because of their dynamic nature. Therefore, host-guest interactions, along with other noncovalent interactions including hydrophobic effects, π-π stacking and multiple hydrogen bonding, were also used for adjusting the intensities and wavelengths of phosphorescence or fluorescence, achieving diverse luminescence properties that the luminophore itself does not possess. This account summarizes the above advances and proposes possible directions for further research, like not only improving quantum yields but also expanding the range of emission wavelength of organic phosphorescent materials and developing luminescent materials that can intelligently respond to external stimuli.
