Two classes of specific binding sites in the polymer matrix were investigated by Scatchard analysis, which indicated that two kinds of complexes between functional monomers and templates were formed before the polymerization process. Comparing with the structure of TNT and acrylamide, one kind of complex between TNT and acrylamide was strongly charge-transfer complexing interaction by p-πcomplex between electron-rich amino group of acrylamide and electron-deficiecy-benzene ring of TNT, the other was hydrogen bonding interaction between amino group (-NH_2) of acrylamide molecule nitro group (-NO_2) of TNT.

Scatchard分析结果表明，在TNT印记聚合物微球中存在两类结合位点，这表明在聚合反应之前，TNT与功能单体丙烯酰胺分子之间存在两种不同类型的作用力而自组装成两类的模板分子-功能单体复合物，一类可能是由于富电子的丙烯酰胺和缺电子的TNT的苯环通过p-π配键而形成的电荷转移复合物，另一类可能是由于丙烯酰胺的胺基与TNT的硝基之间的氢键作用而形成的复合物。

The copolycondesation type polyamic acid was synthesized by using pyromellitic dianhydride and 3,3',4,4'-benzophenonetetracarboxylic dianhydride as the dianhydride monomers, 4,4'-diamino diphenylmethane and 4,4'-oxydianiline as the diamine monomers under microwave irradiation in dimethylformamide.
