Description:
Bisphenoxyethanolfluorene (BPEF) is a specialized diol monomer known formally as 9,9-bis[4-(2-hydroxyethoxy)phenyl]fluorene. Supplied typically as a white solid, BPEF is characterized by its core fluorene structure functionalized with hydroxyethoxy groups. This unique structure makes it a valuable component in synthesizing high-performance polymers. It imparts properties like high refractive index, excellent thermal stability, and good optical clarity, while the ethoxy groups can aid in solubility and processing. As a supplier, we offer high-quality BPEF for advanced material applications.
