The article conveys some information:
The reversible transformation of multicomponent nanorotors (ROT-1, k298 = 44 kHz or ROT-2, k298 = 61 kHz) to the “”dimeric”” supramol. structures (DS-1 or DS-2, k298 = 0.60 kHz) was triggered by a stoichiometric chem. stimulus. Simple coordination changes at the central phenanthroline of the mol. device by altering metal ions (Cu+ → Zn2+) or stoichiometry (Cu+, 1 equiv → 0.5 equiv) affected the terminal zinc(II) porphyrin units, the active sites within the machinery, changing rotational, catalytic and optical properties. In presence of added pyrrolidine, the nanorotor ROT-1 was inactive for catalysis whereas formation of the dimeric supramol. structures DS-1 initiated a Michael addition reaction by releasing the organo-catalyst from the porphyrin sites. This catalytic machinery (ROT-1 → DS-1) proved to reproducibly work over two full cycles using allosteric OFF/ON control of catalysis.4-Iodopyridine(cas: 15854-87-2Category: iodides-buliding-blocks) was used in this study.
4-Iodopyridine(cas: 15854-87-2) is a halogenated heterocycle that is a building block for proteomics research. 4-Iodopyridine is used as a reagent in the synthesis of indazolylamides as glucocorticoid receptor agonists.Category: iodides-buliding-blocks
