When was MOF invented?

First developed in the 1990s, MOFs are crystalline hybrid materials created from both organic and inorganic molecules via molecular self-assembly.

What does MOF mean?

Which metals are used in MOF?

Currently, the most common metal ions used in MOFs include Zn(II), Co(II), Cu(II), Fe(III), and Zr(IV), while the most common organic linkers used in MOFs include terephthalic acid (1,4-benzenedicarboxylic acid), trimesic acid (benzene-1,3,5-tricarboxylic acid), or 2-methylimidazole [38]. …

What is MOF made of?

MOFs are composed of two major components: a metal ion or cluster of metal ions and an organic molecule called a linker. For this reason, the materials are often referred to as hybrid organic–inorganic materials; however, this terminology has recently been explicitly discouraged.

What is a structural analog?

A structural analog can be imagined to be formed, at least theoretically, from the other compound. Structural analogs are often isoelectronic . Despite a high chemical similarity, structural analogs are not necessarily functional analogs and can have very different physical, chemical, biochemical, or pharmacological properties.

What is an analogous structure in anatomy?

In anatomy, two anatomical structures are considered to be analogous when they serve similar functions but are not evolutionarily related, such as the legs of vertebrates and the legs of insects. Analogous structures are the result of convergent evolution and should be contrasted with homologous structures.

What is the meaning of analogue?

Analogy (from Greek analogia, “proportion”, from ana- “upon, according to” [also “against”, “anew”] + logos “ratio” [also “word, speech, reckoning”]) is a cognitive process of transferring information or meaning from a particular subject (the analog, or source) to another (the target), or a linguistic expression corresponding to such a process.

What is an analogous object?

Analogous objects did not share necessarily a relation, but also an idea, a pattern, a regularity, an attribute, an effect or a philosophy. These authors also accepted that comparisons, metaphors and “images” (allegories) could be used as arguments, and sometimes they called them analogies.
