Room-temperature phosphorescence (RTP) can not only intuitively reflect the excited state transition process of the phosphorescent luminescence, but also has wide potential applications in optoelectronics, sensing, bioimaging and security devices. Consequently, more and more attention and interests on RTP materials have been attracted, which turned it to be one of hot topics in luminescence materials, especially, organic luminescence materials in recent years. The halogen bonds and hydrogen bonds between the molecules can fix the phosphor to suppress non-radiative transitions. A twisted donor-acceptor skeleton can promot efficient thermally activated delayed fluorescence (TADF) and also benefit to the RTP. Moreover, circularly polarized room-temperature phosphorescence (CP-RTP) also remains a daunting challenge to implant circularly polarized luminescence (CPL) in metal-free RTP materials. This review summarizes recent research progress on RTP of small organic molecules, mainly focusing on RTP materials based on hydrogen bonds, RTP materials containing halogens, RTP materials based on D-A structures and RTP materials with CPL properties.

Key words: room-temperature phosphorescence, organic small molecule, circularly polarized luminescence
