To enhance the performance of organic field-effect transistors (OFETs), it is crucial to achieve two-dimensional charge transport. In this study, we focus on a unique crystal structure of tetrabenzoporphyrin (Ph-TBP), in which two distinct herringbone (HB) motifs are alternately stacked with orthogonal packing directions—referred to as the “Alternating Layered Herringbone Structure.” This structure is obtained by thermal treatment of a co-crystal with o-dichlorobenzene, and it exhibits excellent charge mobility both theoretically and experimentally.
