In recent years, some natural and synthetic non-conjugated luminescence systems have attracted much attention. However, the phosphorescence properties of these materials are generally not very satisfactory due to the lack of special molecular design. In this work, phosphoramidic acid is introduced into the oligomer matrix to construct a non-conjugated photoluminescence system with ultralong phosphorescence lifetimes up to 376.5 and 776.9 ms and high phosphorescence quantum yield (4.6-10.5%). At the same time, the new system also displays good thermo-processing properties, vitreous solid and optical waveguide behavior.
