Four-Component Supramolecular Nanorotors was written by Samanta, Soumen K.;Schmittel, Michael. And the article was included in Journal of the American Chemical Society in 2013.Formula: C10H12I2 This article mentions the following:
A family of supramol. four-component nanorotors was quant. self-assembled from two different Zn(II) porphyrins: one representing the stator and the other the rotator with DABCO as an interconnecting axle and Cu(I) ions. Rotational spinning in ROT-1′ occurs at 97,000 s-1 at 25鎺?but is virtually stopped at -75鎺? The activation vs. binding data suggest that spinning is an intrasupramol. process occurring to >99.9% without dissociation Addition and removal of two further equiv of Cu+ reversibly switches the mode of the stochastic rotation between pure 180鎺?and mixed 90鎺?180鎺?steps and reversibly regulates the speed between 97,000 and 閳?0,000 s-1. In the experiment, the researchers used many compounds, for example, 1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1Formula: C10H12I2).
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. The C閳ユ彂 bond is the weakest of the carbon閳ユ従alogen bonds. These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I.Formula: C10H12I2
