Phosphorescence Emission

A new doped system with pure phosphorescent emission is constructed using four 1-(4-(diphenylamino)phenyl)-2-phenylethan-1-one derivatives containing halogen atoms as the guests and benzophenone as the host. That is, the doped system...

Room Temperature Phosphorescence

We report an ultralong room-temperature phosphorescence (2.62 s) based on cucurbit[6]uril host and phenyl-methyl-pyridinium guest for data encryption. Encapsulation of CB[6] boosts intersystem crossing and suppresses nonradiative relaxation of guest.
