New types of polyamides containing pendent triaryl pyridine groups were successfully synthesized by direct polycondensation of a symmetry diamine, (4-(4-(2,6-diphenylpyridin-4yl)phenoxy)phenyl)-3,5-diaminobezamide (DPDAB), and various aromatic and aliphatic dicarboxylic diacids in NMP using triphenyl phosphate (TPP) and pyridine as catalyst. The diamine and all the prepared polyamides were fully characterized by using FT-IR, 1H-NMR, UV-Vis spectroscopy, fluorimetry and elemental analysis. The inherent viscosity of polyamides ranged from 0.45 dL/g to 0.68 dL/g. All the polymers exhibited solubility in common polar aprotic solvents such as NMP, DMAc, DMF, DMSO, pyridine, HMPA, and even in less polar solvents such as THF and m-cresol at room temperature. Thermal properties of polyamides were evaluated by means of DSC, DMTA and TGA. These polymers showed glass transition temperatures (Tg) in the range of 138-210C. Their initial decomposition temperature (Ti) varied from 265C to 310C under N2. The dilute solution (0.2 g/dL) of polyamides in DMF exhibited fluorescence emission with max in the range of 470-550 nm.
