The diverse functionalities of large N‐heteroacenes continue to be developed in terms of their strategic synthesis and application in the organic electronic field. Here, we report a novel large stable pyrene‐containing N‐heteroacene with ten linearly‐annulated rings in one row. Remarkably, it exhibited excellent tri‐state resistive memory property, which held great promise to achieve ultrahigh‐density data storage. To the best of our knowledge, it is the first demonstration of organic multistate memory device based on large N‐heteroacene (n≥10), which provides guidelines for designing more proof‐of‐concept larger N‐heteroacene‐based memory electronics.
