“…Metallopolymers MP33-MP34 based on polycarbazole with complexes of 8-hydroxyquinoline in the backbone are also useful for DSSCs. 64,65 These photosensitizers with D-π-A structures use polycarbazole as a donor, a CvN electronwithdrawing spacer as the π-bridge and a complex of 8-hydroxyquinoline with Zn(II), Ni(II) or Cd(II) as an acceptor. MP33-1 and MP33-2 have two absorption bands centered at about 350-374 and 427-447 nm.…”

With the world awareness of energy crisis and low carbon economy, there is an ever-growing demand for renewable energy resources, energy saving products and reliable energy storage devices. Metallopolymers play an increasingly important role as functional materials for energy production, conservation and storage. In this review, we explore the recent advances of metallopolymers in the areas of organic solar cells, white light organic light-emitting diodes and lithium-ion batteries. The structure-property relationship of these polymers and their device performance are specially emphasized and described.Energy storage techniques, especially the lithium-ion batteries (LIBs), are of great importance in the mobile society today due to their high energy density and high output voltage. Although the LIBs that are commonly used nowadays are dominated by inorganic metal complexes in the electronic device market, the rapid progress in portable electronics, such as the ultra-thin, ultra-lightweight and flexible devices, brings new challenges to the bulky and rigid conventional LIBs. 8 For the sake of matching practical requirements and market demands, organic batteries based on redox-active polymers with robust structures have currently become an area of considerable research interest. 9−12On the other hand, lighting consumes over 20% of the total electricity produced in the earth. A majority of such energy consumption and cost comes from the traditional light sources such as incandescent bulbs and fluorescent lamps used in residential, commercial and industrial buildings. Therefore, interest and demand for more energy-efficient products for general lighting purposes is growing rapidly.Organic light-emitting diodes (OLEDs) hold promise for use in display applications and for general illumination for many reasons, including their improved efficiency and low cost. 13 Phosphorescence emissions from metal-containing materials are found to be useful for OLED applications. The efficiency of energy conversion in OLEDs can be enhanced by up to four times, which enable white OLEDs to become a potential new source of "green" solid-state lighting. By embedding metal elements into polymeric scaffolds, both of the physical and chemical characteristics of the resulting organometallic materials can be finely tuned, which combine the optical and 7 Conjugated polymers have received increasing attention as ready-processed organic semiconductor materials. Unlike pure organic conjugated polymers, mixing of metal and ligand orbitals can occur in metallopolymers, which results in special features in these materials. Especially in the Pt(II) acetylenic polymeric framework MP1, π-conjugation of the ligand is preserved through metal 22 and their photophysical properties and photovoltaic responses can be fine-tuned by structural modification of the aromatic spacer (Ar). Due to the presence of Pt(II) heavy metal which induces strong spin-orbit coupling, and thus makes singlet to triplet intersystem crossing to be rapid and efficient, Pt(II) conjugate...

“…Various anchoring groups incorporating in their structure different kinds of bridges/spacers (see Figure ) have been used to anchor porphyrin dyes to the TiO 2 surface, , the most known and used being carboxyphenyl, ethynylcarboxyphenyl, cinnamic, (cyano)phenylacrylic, acrylic, or cyanoacrylic acid groups. Others anchoring groups appear as plausible alternatives for organic dyes in DSSCs, such as catechol, , or more recently rhodanine, azo-bridged salicylic acid, gem-silanediols, tetrazole, pyridyl, − and other related nitrogen containing heterocycles (carboxypyridyl, cyanopyridyl, pyridyl N -oxide, pyridyl N -oxide carboxylic acid, hydroxyquinoline, , benzothienopyridyl, bipyridyl, and pyrimidine). The most studied and widely used remain, however, those based on carboxylic acid, which turned out to give the best performances to date.…”

A waterborne polyurethane-based polymeric dye (WPU-CFBB) was synthesized by anchoring 1, 4-bis(methylamino)anthraquinone (CFBB) to waterborne polyurethane chains. The number molecular weight, glass transition temperature, and average emulsion particle size for the polymeric dye were determined, respectively. This polymeric dye exhibited intriguing optical behaviors. The polymeric dye engendered two new absorption bands centered at about 520 nm and 760 nm if compared with CFBB in UV-vis spectra. The 760 nm peak showed hypsochromic shift with the decrease of average particle sizes. The polymeric dye dramatically demonstrated both hypsochromic and bathochromic effects with increasing temperature. The fluorescence intensity of the polymeric dye was much higher than that of CFBB. It was found that the fluorescence intensities would be enhanced from 20°C to 40°C and then decline from 40°C to 90°C. The fluorescence of the polymeric dye emulsion was very stable and was not sensitive to quenchers.
