Crucial Role of Defect States in the Ultralong Phosphorescence of Organic Molecular Crystals

Xiujuan Duan et al.

Summary: Ultralong organic phosphorescence (UOP) in pure organic molecular crystals has attracted attention, with debates on the emission mechanism. Two recent experimental works attribute UOP in TMOT crystals and carbazole crystals to H-aggregation or charge-transfer excitons. However, first-principles calculations indicate that the lowest triplet states in these crystals are localized defect states. The lack of orbital overlap between these defect states and the crystal band edges is likely responsible for UOP.

Role of Carbonyl Distortions Facilitating Persistent Room- Temperature Phosphorescence

Shuzo Hirata et al.

Summary: A decrease in room-temperature phosphorescence with increasing temperature is explained by increased nonradiative transition caused by molecular vibrations. This study reports that molecular vibrations and distortions contribute positively to phosphorescence characteristics of vanillic acid dispersed in amorphous polymers. The comparison between measured and calculated data suggests that intermolecular processes between vanillic acid and polymers are related to a large decrease in phosphorescence. Vibrational distortions induce mixing between excited and ground states, enhancing the phosphorescence rate compared to the nonradiative transition rate.

Propeller Ultralong Room Temperature Phosphorescence: New Aspect of Triphenylphosphine Derivatives

Wei Gao et al.

Summary: Triphenylphosphine (Ph3P) derivatives are important ligands in catalytic chemistry, and a serendipitous discovery of ultralong room temperature phosphorescence (RTP) in a simple substituted triphenylphosphine (RTP-SDFMU-1) is described. The phosphorescence properties of Ph3P derivatives without heavy atoms and/or carbonyl groups are remarkable both in polycrystalline and powder state. The number of n electrons in the phenyl ring and the molecular packing in the solid state are crucial for the ultralong RTP.

Host-Guest Doping in Flexible Organic Crystals for Room-Temperature Phosphorescence

Yang Xia et al.

Summary: This study proposes a host-guest doping strategy to achieve both room-temperature phosphorescence (RTP) and flexibility in organic single crystals (OSCs). The flexible OSCs exhibit bright deep-red phosphorescence upon external force application and can return to their original shape after stress removal. The results suggest that the bright RTP is due to Forster resonance energy transfer (FRET) from the triphenylene molecules to the dopants. This strategy provides a simple and universal approach for the preparation of flexible OSCs with RTP.
