Electroactive organic molecules have received a lot of attention in the field of electronics because of their fascinating electronic properties, easy functionalization and potential low cost towards their implementation in electronic devices. In recent years, electroactive organic molecules have also emerged as promising building blocks for the design and construction of crystalline porous frameworks such as metal–organic frameworks (MOFs) and covalent‐organic frameworks (COFs) for applications in electronics. Such porous materials present certain additional advantages such as, for example, an immense structural and functional versatility, combination of porosity with multiple electronic properties and the possibility of tuning their physical properties by post‐synthetic modifications. In this Review, we summarize the main electroactive organic building blocks used in the past few years for the design and construction of functional porous materials (MOFs and COFs) for electronics with special emphasis on their electronic structure and function relationships. The different building blocks have been classified based on the electronic nature and main function of the resulting porous frameworks. The design and synthesis of novel electroactive organic molecules is encouraged towards the construction of functional porous frameworks exhibiting new functions and applications in electronics.

“…The incorporation of stable organic radicals thus represents an important tactic for improving long-range charge mobility. 16 Planar MOFs with extended 2D π -conjugation and graphene-like structures are currently among the most conductive frameworks known. These materials exhibit stacked honeycomb lattices that often incorporate benzene or triphenylene-based ligands with square planar metal centers ( Figure 5 ).…”

“…We have successfully demonstrated the versatile use of mesitylene/TMB for the preparation of crystalline materials, apart from its known use for the generation of noncrystalline or partially crystalline mesoporous materials. TMB is not only related to the formation of a polymorphic phase, leading to interesting nanoribbon‐structured frameworks, but more importantly it leads to new results regarding the presence and elimination of radical species17 in hydrothermal reactions that were not known before. The “mesitylene strategy” is anticipated to result in profound effects besides polymorphism and the optical properties discovered in NTHU‐14.…”

The first neutral organo zinc phosphites composed of 2.8 nm-wide ribbons were obtained in pure phases and exhibit near-white-light photoluminescence (PL). By using the "mesitylene strategy", interesting polymorphism in the system of NTHU-14 was discovered. The S-shaped ribbons are arranged into R and L arrays, resulting in RLR and RRR stacking for two polymorphs. p-p interactions exist within each array and hydrogen bonding between adjacent arrays. Besides a common ligand-based emission band at 410 nm, the PL curves of polymorphs 14-a and 14-b are distinctly different: 14a gave a defect-based emission at 565 nm, whereas 14-b primarily shows a p-excimer-based emission at 535 nm. Electron paramagnetic resonance (EPR) data disclosed that radical species exist in the reaction and that the two phases were growing from different environments. Based on these results, the origin of the 565 nm band can be ascribed to lattice defects, and one possible cause of 14-b not showing noticeable yellow emission is identified.Crystalline materials with open-framework structures have shown a great variety of topology, interesting new properties, and multifaceted functionality, and may lead to a better understanding of structure-property relationships as well as to potential applications, particularly energy-related ones. [1] In the past two decades, these materials have been progressively developed from those with inorganic frameworks of aluminosilicates, germanium oxides, and phosphorus-based metal phosphates/phosphites (MPOs) [2, 3] to those with organic-inorganic hybrid structures such as coordination polymers and metal-organic frameworks (MOFs). [4] Strategically, the successful formation of structures with either pure inorganic or hybrid frameworks usually requires the use of organic chemicals as structure-directing reagents or templates. Recently, a major breakthrough in mesoporous inorganic frameworks in the MPO system has been achieved with the 56-, 64-, and 72-membered-ring channel structures of NTHU-13, in which the inorganic mesoporous channel is firstly shown to possess a completely crystalline ordered porewall structure. [5] In addition to the usual organic amine templates, the organic reagent mesitylene (1,3,5-trimethyl-benzene, TMB) was introduced for channel expansion.
