The synthesis of new naphthalene based PFCB aryl ether polymeric isomers with 1,5-, 1,6-, 2,6- and 2,7-linkages was described. Monomers of perfluorocyclobutane (PFCB) poly aryl ethers, 1,5-, 1,6-, 2,6-, 2,7-bis(trifluorovinyloxy)naphthalene, were easily synthesized from hydroxyl groups in two steps and polymerized in the neat without the need for a catalyst or initiator by cyclopolymerization. The naphthalene based PFCB polymers (PFN) had a relatively high Tg in the range 106 - 144 °C and excellent thermal stability at temperature up to 400 °C. The PFCB isomer polymers showed tunability in refractive index and the birefringence of the order of 1,5< 1,6< 2,6< 2,7-PFN and 1,5< 1,6< 2,7< 2,6-PFN, respectively. Plastic optical fibers of homopolymers, 1,5- and 2,7-PFN, and co-polymers, 1,5-co-2,7-PFN and 2,7-PFN-co-6F-PF, were prepared, and optical losses and windows of them were observed. The attenuation loss of naphthalene based PFCB polymers was about 0.17 - 0.27 dB/cm at the wavelength of optical source.
