Synthesis of metal-organic frameworks: A mini review

Metal organic frameworks (MOFs) are a class of crystalline or-ganic-inorganic hybrid compounds formed by coordination of metal clusters or ions with organic linkers, in which bivalent or trivalent aromatic carboxylic acids or N-containing aromatics are commonly used to form frameworks with zinc, copper, chromium, aluminum,

(Obviously ketones and acids do not have these peaks). Diagram 12-9a, Carboxylic acids also have very strong O-H absorptions, seen as very broad peaks around 3000cm-1. Figure 12-10 (SLIDE) Resonance Lowering of Frequencies Just as conjugation (resonance) lowers the stretching frequency of C=C, the same is true for C=O double bonds.

DNA EXTRACTION METHODS

ORGANIC EXTRACTION •Perhaps the most basic of all procedures in forensic molecular biology is the purification of DNA. •The key step, the removal of proteins, can often be carried out simply by extracting aqueous solutions of nucleic acids with phenol and/or chloroform. Dr.L.Yatawara
