Synthesis and characterization of new polyamides and polyimides derived from (E)-9-[β-(2,4-diaminophenyl)vinyl]anthracene

摘要: A new anthracene-containing diamine, (E)-9-[β-(2,4-diaminophenyl)vinyl]anthracene, was prepared and used for the synthesis of a series polyamides polyimides by low temperature solution polycondensation. The polymers were highly amorphous, soluble in aprotic solvents gave films with good optical quality on spin-casting. showed 10% weight loss at 415–460°C under nitrogen. exhibited an intense luminescence region 450–500 nm due emission from excited state diamine moiety. It shown that charge-transfer (CT) interactions negligibly small both ground state, probably to bulky fragment together rigid polymer backbone.
