Polyamides (PAs) containing fluorene, oxyether, and diphenyl-silane moieties in the repeating unit were synthesized in > 85% yield by direct polycondesation between a diamine and four dicarboxylic acids. Alternatively, one PA was synthesized from an acid dichloride. The diamine 4-[4-[9-[4-(4-aminophenoxy)-3-methyl-phenyl]fluoren-9-yl]-2-methyl-phenoxy]aniline (3) was obtained from the corresponding dinitro compound, which was synthesized by nucleophilic aromatic halogen displacement from p-chloronitrobenzene and 9,9-bis (4-hydroxy-3-methyl-phenyl)fluorene (1). Monomers and polymers were characterized by FTIR and C range by DSC analysis. Thermal decomposition temperature (TDT 10% ) values were above 400 C due to the presence of the aromatic rings in the diamine. All PAs showed good transparency in the visible region (>88% at 400 nm) due to the incorporation of the fluorene moiety.
