Remarkable Mg2+-selective emission of an azacrown receptor based on Ir(III) complex was written by Brandel, Jeremy;Sairenji, Masaki;Ichikawa, Kyoko;Nabeshima, Tatsuya. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2010.Application of 66943-05-3 This article mentions the following:
A new aza-15-crown-5 ether-appended iridium complex was synthesized and showed promising on-off selective emission-triggering by inhibition of photoinduced electron transfer (PET) upon binding of Mg2+. In the experiment, the researchers used many compounds, for example, 1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3Application of 66943-05-3).
1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. But on the other hand, ethers undergo cleavage by reaction with acids. Ethers feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. The barrier to rotation about the C–O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3.Application of 66943-05-3
