“…COFs can be attached through a variety of methods, such as the boronate esters, triazines, azine bonds, β-ketoenamines, etc. In 2015, Jin et al reported a series of donor-acceptor COFs named D CuPc -A PyrDI -COF, D NiPc -A PyrDI -COF, D CuPc -A NDI -COF, D NiPc -A NDI -COF, D CuPc -A PDI -COF, and D ZnPc -A PDI -COF with pore sizes of 3.6, 3.6, 3.6, 3.6, 4.0, and 4.0 nm [38] . These COFs with boronate ester linkage were applied in rapid photoinduced electron transfer and charge separation.…”

In recent years, covalent organic frameworks (COFs) as designable crystalline porous polymers have attracted widespread attention because of their tunable structures and functionalities. In particular, the unique characteristics of COFs, such as readily controllable pore size, high surface area, editable pore surface environment, and exceptional chemical stability, provide a structural basis for loading large-sized organic, inorganic, and biological molecules for hetero-catalysis, energy storage, and other applications. In this review, we discuss state-of-the-art strategies for the structural design and synthesis, properties, and functionalities of large pore size two-dimensional and three-dimensional COFs, spotlighting recent breakthrough achievements and remarkable progress to guide further efforts in this field.

Metal‐organic frameworks (MOFs) are a specific class of hybrid, crystalline, nano‐porous materials made of metal‐ion‐based ‘nodes’ and organic linkers. Most of the studies on MOFs largely focused on porosity, chemical and structural diversity, gas sorption, sensing, drug delivery, catalysis, and separation applications. In contrast, much less reports paid attention to understanding and tuning the electrical properties of MOFs. Poor electrical conductivity of MOFs (~10‐7 – 10‐10 Scm‐1), reported in earlier studies, impeded their applications in electronics, optoelectronics, and renewable energy storage. To overcome this drawback, the MOF community has adopted several intriguing strategies for electronic applications. The present review focuses on creatively designed bulk MOFs and surface‐anchored MOFs (SURMOFs) with different metal nodes (from transition metals to lanthanides), ligand functionalities, and doping entities, allowing tuning and enhancement of electrical conductivity. Diverse platforms for MOFs‐based electronic device fabrications, conductivity measurements, and underlying charge transport mechanisms are also addressed. Overall, the review highlights the pros and cons of MOFs‐based electronics (MOFtronics), followed by an analysis of the future directions of research, including optimization of the MOF compositions, heterostructures, electrical contacts, device stacking, and further relevant options which can be of interest for MOF researchers and result in improved devices performance.
