A series of chromophore-functionalized polyimide prepolymers with excellent processibility were prepared by a Michael addition reaction of diamine chromophore 2 with structurally different bismaleimide (BMI) monomers. The effects of the BMI moiety's structure and thermal curing condition on glass tr
Side-chain second-order nonlinear optical polyimides were prepared from four novel chromophore-containing diamines and 4,4Π-(hexafluoroisopropylidene) diphthalic anhydride by a traditional two-step process that included a solution polycondensation followed by a chemical imidization. The four diamine
A thermal stable aromatic polyimide (PI) with side-chain second-order nonlinear optical (NLO) chromophores has been developed. The PI was prepared by the ring-opening polyaddition of 4,4Π-(hexafluoroisopropylidene)diphthalic anhydride with a new diamine having two N-ethyl-N-[4-[(6-chlorobenzothiazol
## Abstract A highly thermally and temporally stable, secondβorder, nonlinearβoptical polyimide with an Xβtype chromophore (2β{4β[4,5βdi(4βnitrophenyl)imidazolyl]phenyl}β4,5βdi(4βaminophenyl)imidazole) was synthesized by the Michael addition reaction. The structure of the prepolymer was characteriz
