An efficient method to decrease dielectric constant (ε) of poly(2,6-dihydroxy-1,5-naphthylene) (PDHN) by introducing bulky alkyl side chains was reported. Poly(2,6-dialkoxy-1,5-naphthylene)s (PDANs) were prepared by the O-alkylation of PDHN with alkyl halides. The ε values of PDANs at 10 GHz decreased as the length and size of side chains increased. Especially, PDCHMN exhibited the lowest dielectric constant (ε = 2.29). The ε value results were also supported by refractive index measurement.
