A Photoconductive Covalent Organic Framework: Self-Condensed Arene Cubes Composed of Eclipsed 2D Polypyrene Sheets for Photocurrent Generation

摘要

Covalent organic frameworks (COFs) are porous crystalline materials with predesignable 2D and 3D polymer structures. Owing to the covalent linkage of the components, as well as the elaborate control of structural parameters, including porosity and composition, COFs are promising for the design of tailor-made porous materials for gas stora-ge We recently reported the cocondensation of triphe-nylene and pyrene monomers to create a semiconducting it-conjugated COF (TP-COF). The well-defined crystalline structure of COFs should have a high probability of forming a conduction path that transports charge carriers across the framework.
