Microwave-assisted synthesis of thiazolothiazole-containing conjugated polymers as promising charge-transport materials for perovskite solar cells

The synthesis of novel thiazolo[5,4-d]thiazole-containing conjugated polymer was performed by three alternative methods, namely, by the Stille or Suzuki cross-coupling as well as microwave-assisted condensation reaction with carbonyl precursor and dithioxamide. The latter way is straightforward and efficient for the design of novel materials with desirable optoelectronic and physicochemical characteristics providing an encouraging hole-transport properties and comparable performance of perovskite solar cells.
