Synthesis of a Triamine Containing a Symmetrical Triarylpyridine Structure and Its Hyperbranched Polyimide

The invention relates to synthesis of a triamine containing a symmetrical triaryl pyridine structure and hyperbranched polyimide thereof. The triamine monomer is BB'2-type aromatic triamine, namely 2,4,6-tris[4-(4-aminophenoxy)-phenyl] pyridine the structure of which is shown in the specification. The triamine is prepared by the following three steps: firstly reacting p-hydroxybenzaldehyde with p-hydroxyacetophenone in acetic acid to obtain 2,4,6-tris(4-hydroxyphenyl) pyridine, then reacting 2,4,6-tris(4-hydroxyphenyl) pyridine with p-chloronitrobenzene to obtain 2,4,6-tris[4-(4-nitrophenoxy)-phenyl] pyridine, and finally reducing the trinitro compound by use of hydrazine hydrate in the presence of a carbon-supported palladium catalyst to synthesize 2,4,6-tris[4-(4-aminophenoxy)-phenyl] pyridine. The hyperbranched polyimide of the triamine is an amino-terminated or anhydride-terminated hyperbranched polyimide polymer obtained by polymerization of the triamine monomer and a commercial dianhydride monomer. The prepared hyperbranched polyimide has excellent high-temperature resistance, solubility and optical properties; and the hyperbranched polyimide polymer material has great application value and prospects in the fields of photosensitive, optical waveguide and gas permeation separation membranes and other materials.
