Problems solved by technology

[0023] In addition, even for substances with similar bandgap, LUMO, HOMO energy levels, the electron mobility and hole mobility effects brought about by the substituted substituents are still not fully demonstrated
[0024] As such, there are many factors that affect efficiency and lifetime depending on the way energy is transferred from the host material to the dopant species, and energy transfer varies from species to species, and is currently used to stabilize high-efficiency electronic components The host material has not been fully developed
