(9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide), abbreviated as DOPO, is used as a reactant in the synthesis of antibacterial agents, antioxidants, anti-fading agents, flame retardants, and monomers. At present, in the field of flame retardants, DOPO is widely used as a new generation of halogen-free, environmentally friendly and green flame-retardant modified monomer.
DOPO is mainly applied in flame retardancy, special functional polymers, epoxy resins, luminescent materials, modified materials and other fields, especially in electronic and electrical materials. In terms of luminescent materials, DOPO can be used to modify luminescent materials and synthesize a new generation of polymers with excellent thermal stability, flame retardancy and physical and mechanical properties, which are used in the manufacture of liquid crystal panels.
