摘要：

A novel thieno[1,4]benzothiazine donor has been developed for the first time to construct metal-free organic sensitizers, which exhibit more dramatically red-shifted absorptions than phenothiazine-based dyes. Under AM 1.5G irradiation, the conversion efficiency of the new dye TBT-1-based DSSC (eta = 7.6%) approximates to that of the phenothiazine-based PT-C-6, indicating thieno[1,4]benzothiazine would be a promising electron donor for the construction of organic optoelectronic materials.
