Our research laboratories have successfully demonstrated the synthesis of semi-fluorinated aryl ether polymers which include perfluorocyclobutyl (PFCB) aryl ether polymers prepared via radical-mediated thermal cyclodimerization of trifluorovinyl ethers (TFVE).1-2 PFCBs have been widely explored for high performance passive-optics, electro-optics, polymer light-emitting diodes, space survivability, polymeric fuel cell membranes, high use temperature fluorosilicones, and liquid-crystalline polymers. We have also demonstrated the nucleophilic addition of bisphenols to TFVEs affording fluoro-arylene vinylene ether (FAVE) polymers.3 Perfluorocycloalkyenyl (PFCA) aryl ether homopolymers and copolymers were prepared in one step via nucleophilic addition/elimination of bisphenols and perfluorocycloalkenes.4 Current efforts in our group are focused on TFVE functionalization of curved-surface polyaromatic hydrocarbons e.g. acenapthenequinone, corannulene or buckybowl-type substrates. The solution and solid state characterization including optical, thermal, and electronic properties of these new materials is presented.
