Abstract
Covalent organic framework materials have recently garnered significant interest from the scientific community due to their fascinating properties that include highly ordered porosity, structural versatility, high chemical and thermal stabilities, and facile surface modification. Herein, for the first time, we present the design and fabrication of a self-powered blue-light photodetector based on boronate-ester-linked 2D covalent organic framework (COF-5) film, synthesized using hexahydroxytriphenylene and 1,4-phenylenediboronic acid organic linkers. Specifically, we have developed a COF-5/n-Si photodetector that exhibits an ultra-short rise response time of 41 µs and a decay response time of 222 µs under 0 V bias. Our work integrated rapid response times and the distinctive benefit of self-powering, setting it apart from existing COF-based photodetectors.
