产品名称：ossila材料6FAP

2,2-Bis(3-amino-4-hydroxyphenyl)hexafluoropropane (6FAP), CAS number 83558-87-6, has two aminophenols bridged by a hexafluoropropane. Like other diamine compounds, 2,2-bis(3-amino-4-hydroxyphenyl)hexafluoropropane reacts with dicarboxylic anhydride to form polyimide membranes showing gas selectivity for hydrogen with ultrafine microporosity. Those fluorinated membranes have high proton conductivity along with good chemical and thermal stability, making it optimal to be used in fuel cell systems. The polyimides synthesized from 6FAP exhibit photosensitivity as second order nonlinear optical properties. After the formation of polyimides, there are unreacted hydroxy groups on the polymer backbone. Therefore, graft polyimides can be obtained through further Mitsunobu reaction or condensation reactions.

In the molecular structure of 6FAP, the hydroxy and amine groups are at ortho-position to each other, so it is perfect for synthesizing polybenzoxazoles for semiconductor manufacturing applications.
