5,6-bis(octyloxy)benzo[c][1,2,5]thiadiazole-bridged dyes for dye-sensitized solar cells with high open-circuit voltage performance

Three new metal-free dyes with a 5,6-bis(octyloxy)benzo[c][1,2,5] thiadiazole core (DOBT-I-III) have been designed and synthesized for use as DSSCs. Their absorption properties and electrochemical and photovoltaic performances have been investigated syste

Thiazolothiazole-based conjugated polymers for blade-coated organic solar cells processed from an environment-friendly solvent

High efficiencies of organic solar cells (OSCs) are generally achieved for small-area devices processed from halogenated solvents, which are hazardous to human health and pollute the environment. Commercialization of OSCs requires the development of novel photovoltaic materials, which are suitable for large-scale fabrication of devices through printable techniques using environmentally-friendly solvents. In this work, we report the synthesis of two novel polymers comprising thiazolothiazole, benzothiadiazole (P1), and benzoxadiazole (P2) moieties and the fabrication of polymer-fullerene OSCs and photovoltaic modules by blade coating under ambient conditions. The P1-based solar cells and larger area modules showed tolerance to processing solvents and delivered encouraging efficiencies illustrating polymer P1 as a promising material for environment friendly large-area photovoltaics.

A Novel Conjugated Polymer Consists of Benzimidazole and Benzothiadiazole: Synthesis, Photophysics Properties, and Sensing Properties for Pd2+

A conjugated polymer PPBIBTE based on benzimidazole and benzothiadiazole was synthesized through palladium-catalyzed sonogashira cross-coupling reaction. The chemical structures of the monomers and the polymer were indicated by 1H NMR, and investigation of photophysics properties and sensing optical properties for metal ions were observed by ultraviolet–visible and photoluminescence spectroscopy. PPBIBTE showed remarkable selectivity for Pd2+ by “turn-off” fluorescence sensing progress. In addition, the Stern–Volmer and Benesi-Hildebrand plots were used to reveal the interaction between the polymer and Pd2+, while job's method was applied to calculate the determination of stoichiometry. The results demonstrate that PPBIBTE can utilize static quenching for Pd2+ by forming a 1:1 complex. And it is a potential sensing material as fluorescence chemosensor for Pd2+ with high selectivity and sensitivity.
