“…[1][2][3] However, in spite of having excellent combination of properties, most of these high-performance polymers have some serious drawbacks, for example, insolubility in common organic solvents, intractability, infusibility, and strong color that often limit their utility in various advanced technological applications. In order to meet these requirements, structural modifications of these polymers often become essential.…”

A photoactive highly fluorinated diamine was synthesized, characterized, and used in preparation of structurally confirmed poly(imidazole-ether-imide)s (PIEIs). These polymers showed excellent solubility, moderate viscosities, good thermal stability (T g = 230-280°C, T i = 390-435°C, T 10% = 480-510°C), low dielectric constant (2.60-2.76), and water absorptions. The PIEIs films showed highly optical transparency with light transmittance at 550 nm of as high as 80% and cutoff wavelength of as low as 390 nm. These polymers exhibited fluorescence emission peaks around 410-490 nm with the quantum yields measured in solution varied from 12 to 32%.

“…Compared with their low molecular weight model compounds, triarylamine derivative bearing conductive polymers show good film forming capabilities, which may render them suitable for the fabrication of large area and flexible OLEDs by both spin coating and inkjet printing methods . Two types of triarylamine‐based polymers have been reported: main‐chain and side‐chain . The side‐chain polymers enjoy greater flexibility in tuning the physical, mechanical and rheological properties by simply varying the chemistry of the triarylamine moiety or by copolymerization with another kind of conducting/luminescent monomer at different compositions.…”

“…However, the technological applications of PIs are limited associated with infusibility and insolubility, which were caused by the highly regular and rigid polymer backbones and the formation of intermolecular hydrogen bonding, resulting in their poor processability. To overcome these drawbacks, structural modifications of the polymer backbone, such as the introduction of pendent bulky, packing‐disruptive groups into the polymer backbone, have been made to modify the polymer properties, either by lowering the interaction or by reducing the stiffness of the polymer backbone …”

A new diamine monomer containing fluorene unit, 3,5-diamino-N-(9H-fluoren-2-yl)benzamide was successfully synthesized via the condensation of 2-aminofluorene and 3,5-dinitrobenzoyl chloride and subsequent reduction of the dinitro compound. A series of novel aromatic polyimides having pendent fluorenamide moieties were prepared from the reaction of the diamine monomer and various tetracarboxylic dianhydrides by a conventional two-step polymerization process. The polyimides were obtained in quantitative yields with inherent viscosities of 0.33-0.44 dl/g. The resulting polymers dissolved in N-methyl-2-pyrrolidinone, N,N-dimethylacetamide, N, N-dimethylformamide, and dimethyl sulfoxide. The glass transition temperature of these polymers was in the range of 261-289°C. They were fairly stable up to a temperature around 450°C and lost 10% weight in the range of 498-556°C in nitrogen. The UV-vis absorption spectra showed that all of the polymers had absorption maxima around 320 nm. Cyclic voltammograms of the polyimides revealed an oxidation wave with a peak around 1.3 V.
