Photoinduced self-assembly of Pt(II)-linked rings and cages via the photolabilization of a Pt(II)-pyridine bond was written by Yamashita, Ken-ichi;Sato, Kei-ichi;Kawano, Masaki;Fujita, Makoto. And the article was included in New Journal of Chemistry in 2009.Electric Literature of C10H12I2 This article mentions the following:
An inert Pt(II)-pyridine bond is considerably labilized upon UV irradiation On the basis of this phenomenon, kinetically inert Pt(II)-linked coordination rings and cages are formed in high yields from their components by obtaining a kinetically distributed mixture and subsequently equilibrating the mixture into the thermodynamically stable structures upon temporary photolabilization. This method is applicable when the pyridine rings in the ligands are not conjugated with other aromatic rings, in good agreement with DFT calculations that indicate the dependency of the photolability on the π-conjugation of the ligand frameworks. Interruption of π-conjugation either by introducing an methylene linker or by twisting the aromatic rings are effective to accomplish the photoinduced self-assembly. In the experiment, the researchers used many compounds, for example, 1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1Electric Literature of 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. Iodo alkanes participate in a variety of organic synthesis reactions, which include the SimmonsSmith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.Electric Literature of C10H12I2
