World energy needs grow each year. To address global warming and climate changes the search for renewable energy sources with limited greenhouse gas emissions and the development of energy-efficient lighting devices are underway. This Review reports recent progress made in the synthesis and characterization of conjugated polymers based on bridged phenylenes, namely, poly(2,7-fluorene)s, poly(2,7-carbazole)s, and poly(2,7-dibenzosilole)s, for applications in solar cells and white-light-emitting diodes. The main strategies and remaining challenges in the development of reliable and low-cost renewable sources of energy and energy-saving lighting devices are discussed.

“…Recent reports have shown that PVK could be very useful as a host material in white-organic light-emitting diodes (WOLEDs) [29,41], in combination with other layers, because of its high energy blue-emissive singlet excited state and the absence of low energy triplet state [30]. Moreover, PVK has also been used in dye-sensitized solar cells blended with TiO 2 as the electron donor and hole-transporting material [31][32][33][34]42]. The interest has grown up recently because of new promising performances in PCs, FETs, and LEDs for carbazole derivatives and related polymers [35].…”

“…This has been proved by the higher conductivity values obtained for the derivatives bearing an electron-withdrawing group on the nitrogen atom of the carbazole unit that makes the oxidation of the lone pair more difficult. For example, the addition of 4-hexylbenzoyl moieties (42,43) onto the nitrogen atom of the carbazole allowed conductivities of about one order of magnitude higher (10 −1 S cm −1 ) than a carbazole with a regular alkyl chain [73,81]. However, the conductivities are still low compared to polythiophenes.…”

“…Carbazole derivatives are widely used in the field of organic electronics as hole-conducting materials with a wide energy gap, e.g. carbazole-based polymers were used to build dye solar cells [3]; carbazole-based small molecules were employed in blue organic light emitting diodes [4]. In addition, a π-conjugated carbazole macrocycle has recently been synthesized, which self-assembles into columnar structures [5].…”
