Aromatic polyamide dendrons (G0–G2) having amino groups on the periphery were prepared by divergent method. Reaction of G0 aromatic polyamide dendron with isonicotinoyl chloride hydrochloride gave polyamide dendron (G0-2Py) bearing two pyridine groups. The structures of polyamide dendrons were confirmed by IR, ¹H, ¹³C NMR, MALDI-TOF mass spectroscopy. A hydrogen-bonded G0-2Py/poly(acrylic acid) (PAA) 1/2 complex was prepared by mixing G0-2Py with PAA in methanol, followed by removing the solvent. IR spectrum of G0-2Py/PAA 1/2 complex showed characteristic absorptions at 2550 and 1950 cm⁻¹ due to hydrogen bonding. A glass transition temperature (T_g) of G0-2Py/PAA 1/2 complex was observed at 121 °C by DSC measurement, whereas T_gs of G0-2Py (137 °C) and PAA (87 °C) disappeared. T_g of the G0-2Py/PAA complex was dependent on the molar ratio ([Donor]/[Acceptor]). Maximum T_g at 121 °C was observed at a ratio of 1.
