Organic Phosphorescence: Enhancing Ultralong Organic Phosphorescence by Effective π-Type Halogen Bonding (Adv. Funct. Mater. 9/2018)

The wide-spread application of organic phosphoresence materials is yet hampered by an insufficient performance under ambient conditions. Ultralong organic phosphorescence (UOP) efficiency can be improved by an intermolecular π-type halogen bonding construction, as reported by Zhongfu An, Qian Peng, Wei Huang, and their co-workers in article number 1705045. The UOP reaches 13.0% efficiency under ambient conditions, enabling data encryption and decryption under sunlight.
