Research Highlight

In contrast to inorganic semiconductors, organic/polymeric semiconductors usually have limited mobilities owing to their structural nature. Enabling electron conduction with high carrier mobility is especially extremely challenging. Herein, we solve this problem by organizing electron-deficient isoindigo units to form well-ordered yet non-conjugated covalent organic frameworks, constituting two-dimensional polygonal backbones and ordered columnar π arrays via face-to-face stack. Hall effect measurements, time- and frequency-resolved terahertz spectroscopy, as well as theoretical calculations, mutually corroborate exceptional high-rate electron transport via band-like conduction across layers and over the 2D planes in the undoped frameworks. This work thus offers a new regime in high-performance organic/polymeric semiconductors and addresses the key fundamental issue of how carriers transport in COFs (Chem 20217, 3309–3324).
