在微波辐射条件下,采用两步法以3,3',4,4'-二苯酮四羧酸二酐(BTDA)和4,4',4"-三氨基三苯胺(TAPA)为单体,先合成出含三苯胺结构的氨基封端和酐基封端的超支化聚酰胺酸,再经化学亚胺化和热亚胺化分别制得了相应的超支化聚酰亚胺(AM-HBOU和AD-HBPI).FT-IR和1H-NMR验证了所得AM-HBPI和AD-HBPI的分子结构.TG测试表明此两种芳香族HBPI具有优异的热稳定性,N2中10%热失重温度(Td10%)在540℃以上.溶解性测试发现化学亚胺化得到的HBPI具有优良的溶解性能,可以溶于常见的强极性非质子溶剂.此外,它们还具有极佳的紫外-可见光吸收性能和荧光发射性能.
