## Abstract A series of new polyimides containing fluorinated alkoxy side chains are prepared from novel fluorinated alkoxy diamines. The dieletric constant at 1 kHz in the fluorinated polyimides decreases from 3.3 to 2.6 as fluorine content increases. The refractive index also changes from 1.58 to
Aromatic polyimides with side chain nonlinear optical chromophores have been investigated through a facile two-step synthetic route. First, various poly(hydroxy imide)s have been synthesized by direct thermal imidization of diaminophenol dihydrochloride salt and aromatic dianhydride monomers. The re
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 4,4ะ-(hexafluoroisopropylidene)diphthalic anhydride with a new diamine having two N-ethyl-N-[4-[(6-chlorobenzothiazol
