The Inside Cover picture illustrates two different crystalline structures in the solar cell devices. It depicts a series of asymmetric small conjugated molecules based on anthracene that were used in a systematic investigation of the structure–property relationships in solar cell devices prepared by using films of these molecules. One has a naphthalene unit and consists of amorphous domains without crystallites, whereas the other has a thiophene linker, which results in a randomly ordered crystalline structure. We focused on how the thiophene spacer influenced the nanoscale crystalline characteristics of the active layers and the resulting device performances. Our results can be used to guide the design and optimization of new high‐performance anthracene‐based small molecules. More details can be found in the Full Paper by Kim et al. on page 1548 (DOI: 10.1002/cssc.201402994 ).
