| Abstract | A novel BB′ 2-type triamine was synthesized for the first time and employed to prepare a series of amine- and anhydride-terminated triphenylpyridine-containing hyperbranched polyimides under microwave irradiation. The structure of the triamine monomer and polymers were verified by FTIR and 1H NMR spectroscopy. The predominantly amorphous polyimides were soluble inm-cresol, NMP, DMSO, DMAc and DMF at room temperature or upon heating. The polymers showed glass transition temperatures above 310 8C and a 5 and 10% weight-loss temperature above 482 and 559 °C. Tensile strength and modulus were higher than 53.1 MPa and 1.01 GPa, respectively. AM-HBPI- 2 and AD-HBPI-2 showed UV-Vis absorptions in the region 200-400 and 200-350nm and displayed strong purple and blue fluorescence. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. | ||||
