“…13 Carbon nanotubes 14 and gold surfaces for functionalization of self-assembled monolayers 15 have been reported with click chemistry. Recently click chemistry has also been used to synthesize organic dye 16 and polymers 17,18 for DSSCs applications. As an extension of our previous work, 17,18 in the present study, we have synthesized novel phenothiazinebased polymers by click chemistry and their electro-optical properties were investigated.…”

A new series of phenothiazine-based polymeric electrolytes were developed to obtain a high power conversion efficiency (PCE) of dye-sensitized solar cells (DSSCs). Phenothiazine-based click polymers were synthesized using Cu(I)-catalyzed click reaction methods. The resulting polymers were soluble in common organic solvents and had a reasonable molecular weight. The thermal properties, emission spectra, and energy band gap of synthesized click polymers were also investigated. The polymer electrolytes were composed of iodide and triiodide redox species embedded in phenothiazine-based click polymers or polyacrylonitrile (PAN) as a polymer matrix. DSSCs were fabricated with a configuration of SnO 2 :F/TiO 2 /N719 dye/polymer electrolyte/Pt devices using these click polymers or PAN as an electrolyte components and compared photovoltaic performance. The maximum PCE of the phenothiazine-based click polymers as polymer electrolytes for DSSCs was obtained 5.30% (at 1 sun). These enhanced click polymers are expected to find applications as an electrolyte component in DSSCs in the future.

“…This methodology has been applied widely in the fields of organic chemistry, [7] supramolecular chemistry, [8] drug discovery, [9] bioconjugation, [10] materials science, [11][12][13][14] and dye-sensitized solar cells (DSSCs). [15][16][17] Currently, 1,3-dipolar-cycloaddition-based click chemistry has also been the focus of efforts aimed at the synthesis of liquid-crystal polymers. [18] However, the preparation of side-chain liquid-crystal polymers (SCLCPs) by using click chemistry has not been explored.…”

SCLCPs are synthesized using “click chemistry”. The resulting polymers, P1 and P2, have good solubilities and molecular‐weight distributions. Their $\overline {M} _{{\rm w}} $ and polydispersities are in the ranges of 26.7–8.4 × 103 g · mol−1 and 1.99–1.29, respectively. DSC and POM studies reveal that both polymers exhibit liquid‐crystalline behavior. P1 and P2 are found to display blue emission. DSSCs are fabricated using P1 and P2 as matrices for electrolytes. The maximum PCE of the P1‐ and P2‐based polymer electrolytes is 4.11% (at 1 sun). This synthesis route has again proven to be a useful synthetic methodology for fabricating SCLCPs that are promising materials for device applications.magnified image
