Organic thermally-activated delayed fluorescence (TADF) materials have been widely applied in organic optoelectronics, biol. oxygen sensing, fluorescence probes, and imaging. Inspired by sulfonyldibenzene-based TADF materials with considerable charge transport abilities and distorted structures, we design and synthesize three sulfonyldibenzene-based mols. (CS-01, CS-02, and CS-03) as hole transport materials (HTMs) for perovskite solar cells (PSCs). The CS series HTMs are endowed with excellent thermal stability, good solubility, and suitable energy level matched with perovskite material. As a result, the CS-01-based PSC devices deliver an impressive power conversion efficiency (PCE) of 19.94% and excellent thermal stability. In the part of experimental materials, we found many familiar compounds, such as 3,6-Dibromo-9H-carbazole(cas: 6825-20-3Electric Literature of C12H7Br2N)
3,6-Dibromo-9H-carbazole(cas: 6825-20-3) is used as a pharmaceutical intermediate, and also an important intermediate of synthesizing optoelectronic materials. It has been used in the preparation of N-(2-hydroxyethyl)-3,6-dibromocarbazole.Electric Literature of C12H7Br2N
