Abstract
Three classes of semi-fluorinated aromatic ether polymers, namely: perfluorocyclobutyl (PFCB), perfluorocycloalkenes (PFCA), and fluorinated arylene vinylene ether (FAVE), which are mostly amorphous have been reported via step-growth polymerization of fluoroalkenes. Unlike traditional fluoropolymers which have higher degree of crystallinity and are plagued by lack of solubility in common organic solvents, these uncured semi-fluorinated polymers are readily soluble in most organic solvents resulting in improved processability. In addition, all three semi-fluorinated polymers are versatile and can be custom-designed and fabricated into linear, telechelic, alternating and segmented-block, and network polymers, facilitating applications in optics, optoelectronic, photonics, proton exchange membranes, sensors, and fuel cells. Major aim of this timely review is to provide account of synthetic opportunities these semi-fluorinated offer in various applications.
