Triarylamine/bithiophenecopolymers (TABT), synthesized via iron-catalyzed C−H/C−H coupling, have been applied as hole-transporting materials for perovskitesolarcells (PVSCs). Owing to the film uniformity, enhancedquinoidal conjugation in radical cation state, and excellent ionization potential matching, a PVSC using a mesityl substituted TABT polymer outperformed devices using reference standards

system for the high-throughput synthesis, purification, and characterization of molecules with a large variety. Based on the principle “Like dissolves like,” we combine theoretical calculations and a robotic platform to accelerate the purification of those molecules. With this platform, a material library containing 125 molecules and their optical-electronic properties was built within a timeframe of
