9,9-Bis(4-Hydroxyphenyl)fluorene CAS 3236-71-3 Purity >98.0% (HPLC)

9,9-Bis(4-Hydroxyphenyl)fluorene (4,4'-(9-Fluorenylidene)diphenol; Bisphenol FL; BPFL) (CAS: 3236-71-3) is a derivative of fluorene with two hydroxyphenyl moieties attached to adjacent carbon atoms on one of the fluorene rings. It is used as a monomer for the synthesis of different types of polymers, including poly(arylene ether ketones), that find wide application in different industries such as aerospace, automotive, electronics, and coatings. BPFL is also used for the preparation of fluorescent dyes and as a fluorescent probe in biochemical studies. BPFL is also used in the development of advanced electronic materials such as organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs).
9,9-Bis(4-Hydroxyphenyl)fluorene is the monomer and modifier of functional polymer material,it is Cardo skeleton structure bisphenol compound, it is important monomer and modifier of synthesis of fluorene-based epoxy resin, fluorene and benzene benzoxazine resins, acrylic resins, polyester resins, polycarbonate, epoxy, polyester or polyether condensation products. Fluorene-based epoxy resin has excellent humidity resistance and heat resistance, dielectric properties, mechanical properties, chemical resistance, etc., it has been important monomer and modifier of high-performance resin matrix materials, electronic packaging materials, high temperature resistant adhesives, heat resistant coatings, etc. But the rigidity of fluorene-based epoxy resin is better, but toughness is poor, therefore, it need to be modified toughening when be used, or use the method of mixing with general-purpose epoxy resin to modify.
9,9-Bis(4-Hydroxyphenyl)fluorene can be used the intermediate of organic synthesis. Building blocks for organic semiconductor.
9,9-Bis(4-Hydroxyphenyl)fluorene is used in the production of polyarylene ethers and extensively used in the study of polymer electrolyte membranes with the potential for fuel cell application.
Bisphenol FL (BPFL) is a fluorinated derivative of bisphenol (BP), a wide group of chemicals with similar structures, recognized as environmental pollutants. Bisphenol A (BPA), and its structural analogs are widely used as plasticizers and monomers for synthetic materials, industrial and consumer products including fluorine rubber, food container linings, canned food, thermal receipts, etc.
