It is urgent to develop a universal strategy for producing small organic molecules exhibiting efficient room temperature phosphorescence (RTP). An important contribution made by Ma and Tian et al. provides a general and applicable strategy to obtain amorphous organic molecules with efficient RTP emission by simply modifying phosphors onto β‐cyclodextrin (β‐CD). The nonradiative decay processes and oxygen quenching have been significantly suppressed by the strong intermolecular hydrogen bonding between β‐CD derivatives. Furthermore, the cavity of β‐CDs endows them with the ability to incorporate the adamantane moiety of the fluorescent guest molecules to construct a supramolecular system which exhibits excellent RTP‐fluorescence dual emission properties and multicolor emission by altering the host to guest ratio and the excitation wavelength.
