Aqueous phase and amorphous state room temperature phosphorescence from a small aromatic carbonyl derivative

Materials Research Express, 2019
Harvesting triplet excitons via room temperature phosphorescence (RTP) in solution or amorphous state from purely organic chromophores is a formidable challenge. Supramolecular hybrid co-assembly between a brominated aromatic carbonyl derivative ( BrPhS )

Influence of geometry on the emitting properties of 2,3-naphthalimides [PDF]

, 1992
The luminescence properties of 2,3-naphthalimides have been studied using picosecond and nanosecond spectroscopies. In acetonitrile solution N-phenyl-2,3-naphthalimid(e3 ) is found to emit dual fluorescence with emission maxima at 385 and 490 nm ...
