“…In the neutral state, the dihedral angle between thiophene units is of a few degrees. The cation radical species are likely to form more planar conformations, what has been observed for other organic semiconductors [90]. For the studied molecules this phenomenon may also be observed, however for 1 +• the planarization occurs for thiophene rings but not for the central bipyridine unit.…”

“…The PL spectra of films are redshifted compared to blends. Redshift of the λ em from the NMP solution to blend and to film is characteristic also for other polyimides . Probably this redshift of the λ em is due to molecular packing and a stronger intermolecular interaction occurred in the solid state.…”

“…Continuing our effort in the synthesis of polyimides with photoluminescence ability for potential applications in organic optoelectronics in this work we present polyimides containing fluorinated group to afford good both solubility and thermal properties, and various chromophores such as fluorene, anthraquinone, phenylphenanthridine, stilbene, and fluorenylidene derivatives. Their structural (X‐ray diffraction), thermal (thermogravimetric analysis (TGA), differential scanning calorimetry (DSC)), and photophysical properties involving the absorption and emission in solution and in solid state as a blend with nonemissive poly(methyl methacrylate) (PMMA) were investigated.…”

The fluorinated polyimides are synthesized from 4,4′‐(hexafluoroisopropylidene)diphthalic anhydride and various diamines containing fluorene, anthraquinone, phenanthridine, stilbene, and fluorenylidene units. The polymers exhibit high glass transition temperature (Tg = 170–261 °C) and high thermal stability with decomposition temperatures (Td) in the range of 320–560 °C and 290–520 °C in nitrogen atmosphere and in air, respectively. The optical properties, that is, absorption in UV–vis range and photoluminescence of obtained polyimides, are investigated in solution and in solid state as a blend with inert poly(methyl methacrylate). The polymers in solution and in solid state emit light in the range of 356–572 nm depending on the polymer structure. Additionally, the photoluminescence properties of the polyimide containing phenanthridine units in the backbone before and after protonation with HCl and methanesulfonic acid are tested in N‐methyl‐2‐pyrrolidone solution. All polyimides are electrochemically active and undergo an electrochemical reduction process as is found in cyclic voltammetry. The lowest unoccupied molecular orbital (LUMO) levels are found in the range from −3.58 to −3.93 eV.
