In article number 1907242, Kai Xi, Peng Zhan, Fei Xu, Yanqing Lu, and co‐workers report an ultrasensitive photodetector using 2D covalent organic framework (COF)–graphene heterostructures. By selecting photoactive monomers, elaborately designed photosensitive 2D‐COFs with highly ordered donor–acceptor topologies are in situ synthesized on graphene, ultimately forming COF–graphene heterostructures. This study provides new strategies for building advanced functional devices with programmable material structures and diversified regulation methods.
