Novel 2D COFs Derived from Stabilized Acenes as Organic Semiconductors

Two-dimensional covalent organic frameworks (2D COFs) exhibit periodically stacked π-columns and extended conjugation within their layers, promoting robust intralayer electronic interactions and effective interlayer π-delocalization. These electronic interactions provide pathways for charge carrier mobility (holes and electrons) along both the vertical π columns and within the 2D layers. Consequently, 2D COFs represent promising constructs for the design of semiconducting materials with excellent electronic properties. This presentation will describe the synthesis and characterization of 2D COFs using rationally selected π-conjugated units (acene derivatives). Experimental results will be integrated with theoretical (DFT) calculations. We actively seek collaborations in the field of organic electronics, including organic field-effect transistors (OFETs), organic photovoltaics (OPVs), organic photodetectors (OPDs), memory devices, and sensors, before, during, and after the meeting.
