We report an unexpected long room-temperature phosphorescence lifetime of up to 1.0 s by doping iodinated difluoroboron(iii) β-diketonate (IBF2) into phenyl benzoate matrices. In contrast, IBF2 powders alone show insignificant afterglow even at 77 K.

New System

The phosphoramidic acid oligomer as an organic non-conjugated RTP system is proposed. The new system not only has ultralong phosphorescence lifetime up to 777 ms and high quantum yield, but also displays dual-band optical waveguide behavior.
