Abstract:In this work, we have successfully synthesized 15 new examples (LLA01‐06; LinLi01‐10) of small‐molecule hole‐transporting materials (HTM) using the less explored indolocarbazole (ICbz) as core moiety. Different from previously reported ICbz HTMs, LinLi01‐10 exhibit new molecular designs in which 3,4‐ethylenedioxythiophene (EDOT) units are inserted as crucial π‐spacers and fluorine atoms are introdcued into end‐group molecules. These substantially improve the materials solubility and device power conversion eff… Show more
