“…As shown in Figure 1A, 4,4′,4″,4‴-(PyTTA-TPA), 4,4′,4″,4‴-(1,3,6,8-Tetrakis(4aminophenyl)pyrene-[2,2′-Bipyridine]-5,5′-dicarboxaldehyde (PyTTA-BPyDCA), and 4,4′,4″,4‴-(1,3,6,8-Tetrakis(4-aminophenyl)pyrene-4,4′-Biphenyldicarboxaldehyde (PyTTA-BPDA) COF films were synthesized using ambient-pressure CVD. The PyTTA monomer was uniformly loaded onto a clean growth substrate through thermal evaporation, thus allowing precise control of the growth thickness [41] . The substrate with PyTTA was placed in a quartz tube inside a tube furnace, whereas TPA powders were placed in a ceramic boat heated to 80 °C.…”

Humanity is confronting significant environmental issues due to rising energy demands and the unchecked use of fossil fuels. Thus, the strategic employment of sustainable and environmentally friendly energy sources is becoming increasingly vital. Additionally, addressing challenges, such as low reactivity, suboptimal energy efficiency, and restricted selectivity, requires the development of innovative catalysts. Two-dimensional (2D) covalent organic frameworks (COFs), known for their limitless structural versatility, are proving to be important materials in energy conversion applications. The exceptional properties of 2D COFs, including an organized arrangement resulting in well-defined active sites and π-π stacking interactions, enable breakthroughs in sustainable energy conversion applications. In this study, we comprehensively investigate universal synthesis methods and specific techniques, such as membrane-based deposition, liquid-phase intercalation, and polymerization. Furthermore, we demonstrate energy-conversion applications of 2D COFs as eco-friendly catalysts for electrochemical processes to promote sustainability and scalability by utilizing them in the hydrogen evolution reaction, oxygen evolution reaction, oxygen reduction reaction, and carbon dioxide reduction reaction. Additionally, we will explore methods for analyzing the physicochemical properties of precisely fabricated 2D COFs. Despite extensive research pertaining to 2D COFs, their practical industrial applications remain limited. Therefore, we propose various perspectives, including enhancing performance, improving synthesis methods, developing binder-free catalysts, expanding catalyst functionality, and advancing full-cell research, to achieve complete industrialization by leveraging their potential.

Covalent organic frameworks (COFs) are porous materials with good crystallinity, highly ordered stacking, tunable channels, and diverse functional groups that have been demonstrated to show great potential applications in flexible electronic devices, including flexible energy storage devices (batteries and supercapacitors), memristors and sensors. Although great research progress on the usage of COFs as active elements in flexible electronics has been witnessed, the summary in this direction is rare. Thus, it is the right time to write a review on COFs‐based flexible electronics. In this review, we will first discuss the different synthesis strategies to prepare COF materials. Then, the applications of COFs in flexible electronic devices are summarized. Finally, the future performance improvement and development directions of COFs in the field of flexible electronic devices are briefly outlined. This review could provide basic concepts and some guidelines to stimulate novel applications of COFs in diverse flexible electronic devices.
