Perfluorocyclobutyl (PFCB) aryl ether polymers1 have been incorporated into a number of platform technologies including: high performance passive optics, electro-optics, polymer light-emitting diodes (PLEDs), space survivability, and polymeric fuel cell membranes (PEMs), to name a few (Scheme 1).2 Polymerized via a step-growth [2+2] thermal dimerization of aryl trifluorovinyl ether (TFVE) monomers, PFCB polymers offer a unique platform as semifluorinated cyclopolymers. More recently we have explored nucleophilic step growth, semifluorinated polymers from TFVE and perfluorocycloalkenyl monomers to form fluorinated arylene vinylene ether (FAVE)3 and perfluotocycloalkenyl aryl ether (PFCA)4polymers (Scheme 1). Concurrently we explored a class of processable pre-carbon materials from bis-o-diynylarene (BODA) monomers which undergo thermal Bergman cyclo-rearrangement and polymerization to form carbon networks in > 80 % yield with applications in electronics, composites, light emitting diodes, sensors, dielectrics and conductors.5 Additionally this lecture will overview projects in our laboratory on renewable materials, car tire rubber composites, and direct fluorination.(1) Babb, D.
