The Synthesis And Properties Of Diindole Fused Phosphole Derivatives

The materials of phosphorus organic electroluminescence has been a hot area of research in the field of organic photovoltaic materials in recent years, and the unique electronic structure of phosphorous compound often has unique optoelectronic properties. At present, we design and synthesize a series of diindole fused phosphorus compounds, and preliminary study the photoelectric properties of these compounds. Through chemical modification of the phosphorous center(sulfide, oxidation, etc.), and changing the π- conjugate system, the photoelectric properties are regulated. Studies have shown that the fluorescence emission regions of these compounds in blue green area, and the compounds all have good thermal stability and high fluorescence quantity yield. These good performance of the diindole fused phosphorus compounds show good potential applications on organic electroluminescent materials. In addition we studied the relationship between the stacking mode and the luminescence properties.
