“…The vast majority of their applications are related to pore sizes, shapes, flexibility and structures/environments. Particularly interesting are those PCPs where the solid-state properties of the framework (magnetism [417], luminescence [418], conductivity [419–420], charge transport [421], etc.) change upon sorption/desorption of guest molecules.…”

SummaryThe article deals with coordination compounds of iron(II) that may exhibit thermally induced spin transition, known as spin crossover, depending on the nature of the coordinating ligand sphere. Spin transition in such compounds also occurs under pressure and irradiation with light. The spin states involved have different magnetic and optical properties suitable for their detection and characterization. Spin crossover compounds, though known for more than eight decades, have become most attractive in recent years and are extensively studied by chemists and physicists. The switching properties make such materials potential candidates for practical applications in thermal and pressure sensors as well as optical devices.The article begins with a brief description of the principle of molecular spin state switching using simple concepts of ligand field theory. Conditions to be fulfilled in order to observe spin crossover will be explained and general remarks regarding the chemical nature that is important for the occurrence of spin crossover will be made. A subsequent section describes the molecular consequences of spin crossover and the variety of physical techniques usually applied for their characterization. The effects of light irradiation (LIESST) and application of pressure are subjects of two separate sections. The major part of this account concentrates on selected spin crossover compounds of iron(II), with particular emphasis on the chemical and physical influences on the spin crossover behavior. The vast variety of compounds exhibiting this fascinating switching phenomenon encompasses mono-, oligo- and polynuclear iron(II) complexes and cages, polymeric 1D, 2D and 3D systems, nanomaterials, and polyfunctional materials that combine spin crossover with another physical or chemical property.

“…Although TCNQ derivatives have mainly been incorporated as guest molecules in MOFs to enhancee lectrical conductivity, such as the prototypical example of TCNQ@Cu 3 (BTC) 2 reported by Ta lin, Allendorf et al, [46,101,102] there are also many examples of MOFs in which TCNQ has been used as an integral component of the framework to incorporate additional electronic functionalities. [103] In this context,several examples of electrically conductive frameworks have been achievedu sing TCNQ ligands,s uch as the well-known [Cu(TCNQ)], [104] which possesses two structural phases:p hase I( s = 10 À1 Scm À1 )i sm uch more conductive than phaseII( s = 10 À5 Scm À1 )b ecause of the presence of delocalized stacks of mixed-valence TCNQ moieties.

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.

“…Because of the high variability of porosity, surface area, topology, and tunable chemical nature, this class of materials is a rapidly growing area of research . As a result, MOFs are investigated for a variety of potential applications including, gas storage and separations, heterogeneous catalysis, sensing, and drug delivery . It has been shown, that for certain catalyzed reactions the catalytic centers need to be isolated in order to achieve high catalytic activity , .…”

Metal-organic frameworks are one of the most active research fields today. Despite the progress in recent years, synthesis of highly porous structures bearing functional groups for specific applications remains a challenge. Here, we describe synthesis of Zr(IV) and Hf(IV)-based tetrazine containing metalorganic frameworks, ZrTz-68 and HfTz-68 with pore size of 2.1 nm, specific surface area up to 4217 m 2 g -1 , and a UiO-68
