1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1) belongs to iodide derivatives. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles. A typical method for synthesis of aromatic iodides is diazotization of primary aromatic amines followed by treatment of potassium iodide. Aliphatic alcohols are converted to alkyl iodides by treating with hydrogen iodide.Product Details of 3268-21-1

From supramolecular porphyrin tweezers to dynamic AnBmClDk multiporphyrin arrangements through orthogonal coordination was written by Kishore, Ravuri S. K.;Paululat, Thomas;Schmittel, Michael. And the article was included in Chemistry – A European Journal in 2006.Product Details of 3268-21-1 This article mentions the following:

A dynamic, supramol., three-component AnBmC1 bis(zinc porphyrin) tweezer,containing Cu(I), I (R = 2,4,6-trimethylphenyl, R1 = 4-bromo-2,3,5,6-tetramethylphenyl), and II (R2 = dodecyl) was prepared quant. using the heteroleptic bisphenanthroline (HETPHEN) concept. Upon addition of nitrogenous spacers of different length, namely, the extended 1,4-bis(4′-pyridylethynyl)durene (3a), 4,4′-bipyridine (3b), and 1,4-diazabicyclo[2.2.2]octane (DABCO; 3c), to set up an addnl. orthogonal binding motif (ZnPor-Nspacer), three structurally different, still dynamic, four-component AnBmC1Dk assemblies were cleanly formed, as indicated by UV/visible and NMR titrations as well as by DOSY studies. The structures were identified as a bridged monotweezer A2BC2D, a doubly bridged double tweezer A4B2C4D2, and a triply bridged double tweezer A4B2C4D3, the latter resembling a porphyrin stack. Notably, the same structures were equally formed directly from a mixture of the constituents A, B, C, and D put together in any sequence if the correct stoichiometry was applied. In the experiment, the researchers used many compounds, for example, 1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1Product Details of 3268-21-1).
