Suzuki polycondensation and post-polymerization modification toward electro-optic perfluorocyclobutyl (PFCB) aryl ether polymers: Synthesis and characterization

Light-Mediated Atom Transfer Radical Polymerization of Semi-Fluorinated (Meth)acrylates: Facile Access to Functional Materials

“…Given these favorable properties and real-world applications, the development of synthetic techniques for the preparation of well-defined fluorine-containing polymers is of significant interest. Two generic strategies are typically employed: (1) postpolymerization functionalization of non-fluorinated polymers ,− and (2) polymerization of fluorinated monomers. , While the former route is in principle compatible with many polymer backbones, the strategy requires reactive pendant functionality and efficient coupling chemistry. Additionally, all starting materials and intermediate products must remain soluble in the reaction mixture.…”

Acenaphthylene‐derived perfluorocyclobutyl aromatic ether polymers

“…Prepared via thermal cyclopolymerization of aromatic trifluorovinyl ether (TFVE) monomers to give stereo‐random and regioselective 1,2‐disubstituted PFCB enchainment, a wide range of diverse monomer and polymer structures have been accessed primarily due to the advent of metal/halogen exchange reaction from Br‐TFVE precursor . More recent work has focused on high performance optical materials, light emitting diodes, and electro‐optics, proton exchange membrane ionomers, and photovoltaic devices, by simple introduction of backbone functionalities resulting in tailored properties …”

“…Traditionally, PFCB polymers are prepared by the step‐growth, [2 + 2] thermal cyclodimerization of functional trifluorovinylether (TFVE) monomers in melt or in solution. Semifluorinated PFCB polymers are also obtained by polymerization of PFCB containing monomers mediated by classical methods including; Huisgen's 1,3‐dipolar cycloaddition, nucleophilic aromatic substitution, and more recently, by Suzuki polycondensation . Depending on the functionality, branching, and network formation, PFCB polymers typically exhibit high glass transition temperatures ( T g = 150–300+ °C), and thermal stability under air and nitrogen atmospheres T d > 400 °C.…”

Synthesis and characterization of a biphenyl perfluorocyclobutyl (BP‐PFCB) polyethylene glycol (PEG) blend compatibilizer

“…PFCB aryl ether polymers have been investigated for a broad range of applications including microelectronics, [11][12][13] protonexchange membrane fuel cells (PEMFCs), [14] and polymer light emitting diode (PLEDs). [15,16] Polymeric blending is a highly effective method to combine properties and are typically faster than modular approach utilized in PFCB aryl ether polymers. PFCB aryl ether polymers blend with fluorinated materials have been reported.…”

“…PFCB aryl ether polymers are typically amorphous because of the stereorandom head‐to‐head formation of the PFCB linkage. PFCB aryl ether polymers have been investigated for a broad range of applications including microelectronics, proton‐exchange membrane fuel cells (PEMFCs), and polymer light emitting diode (PLEDs) …”
