“…Macromolecules end-capped carbazole moieties were also used as luminescent films electrodeposited (ED) with good electropolymerization behaviors and properties [10]. Likewise, polymers bearing carbazole structure has been widely described [14][15][16][17][18][19], e.g., fluorescent carbazolyl-labeled polysiloxanes [14]. A green light-emitting phosphorescent and polymeric light-emitting diode (PLED), containing a layer of a carbazole-oxadiazole copolymer showed a high efficiency, current densities, and luminance levels [15].…”

“…[16]. High, blue photoluminescence activity of segmented polyethers containing oxadiazole/carbazole units and flexible aliphatic moieties have also been described [17,18]. Furthermore, nonconjugated hybrids of carbazole and fluorine have been investigated as a novel host material for highly efficient phosphorescent OLEDs [19].…”

A series carbazolyl-containing polymers were synthesized by anionic polymerization of various oxiranes and methyl methacrylate. The polymerization was carried out using as initiator carbazylpotassium activated 18-crown-6 in THF. The polymers were prepared and found using size exclusion chromatography to have a degree of polymerization (DP n ) about 20 relatively and low dispersity in the range of 1.07-1.66. Their optical properties were investigated by means of UV-vis and photoluminescence spectroscopies. The obtained polymers emitted light with maximum emission about 370 nm and high quantum yield ranging up to 79 %. Thus, it was confirmed that the utilization of fluorophore initiator for polymerization of non photoresponsive monomers is quite efficient for the preparation of photoluminescent polymers.

We report on the synthesis and the characterization of a new class of segmented polyethers POC containing the oxadiazole and carbazole units. The polymers exhibit a high thermal stability, high glass transition temperatures, and good solubility in common organic solvents, despite the extended aromatic portion in the main polymer chain. The synthetic procedures are simple, and no acid side-products are obtained. According to previous reports on oxadiazole/carbazole-containing materials, POCs show high photoluminescence activity in the blue region of the visible spectra. The good solubility in chlorinate solvents allows the preparation of films with homogeneous thickness by spin coating. Glass transition temperature in the range 115-125• C ensures good stability of film morphology at room temperature. The only exception is POC(6), which shows a poor solubility and higher T g (170• C), due to its shorter aliphatic chain portion. For these features, polymers POC are potential candidate materials for fabricating blue light-emitting devices.
