Inside back cover image: Crystal structure of π-conjugated small molecules and polymers is fundamentally critical to understand the multilevel microstructures. However, determining crystal conjugated remains a significant challenge. Jian Pei coworkers build possible structures eight typical polymers, covering several widely used molecular segments in organic optoelectronics. These are modeled by combining synchrotron X-ray diffractions simulations, which compose database providing new platform predict packing charge transport properties related polymers. Such aims accelerate intelligent design high-performance (DOI: https://doi.org/10.1002/smm2.1053)
