High-entropy materials combine five or more constituents into a single crystalline structure with unique emergent properties. While widely explored in inorganic systems, this concept is only beginning to be harnessed for organic semiconductors (OSCs). We recently demonstrated a proof-of-concept high-entropy OSC formed from a blend of 5 different diphenyl hexatriene derivatives, revealing unexpectedly high crystallinity. Building on this, our proposal targets anthracene-based OSCs to create five-component blends selected from 25 commercially available molecules. Using grazing incidence X-ray scattering (GIXS) at the XMaS beamline, we will systematically screen ~250 distinct formulations to discovering novel high-entropy crystal phases exhibiting enhanced structural order and enhanced electronic properties. By expanding the design space of OSCs and offering a pathway to low-embedded-energy devices, this study paves the way for an entirely new class of organic semiconductor materials.
