WebThe cryptands have the same kind of properties as the crown ethers and the same uses. In general, they form much more strongly bound complexes and can be used to stabilize unusual ionic species. For example, it is possible to produce the negative Na− ion in the compound [(2,2,2)-cryptand-Na]+Na−, which is a gold-coloured crystalline ... WebAs seen in Figure 14 the ellipsoidal cryptands may be prepared by the simultaneous formation of three bridges. This route has found limited use due to low yields but has been employed in the synthesis of some cryptands including the tris-pyridino system (36) 〈81TL3035〉 and bis-tren (18) 〈80UP52100〉.The presence of nitrogen bridgeheads … csusm clubshttp://fanyi.youdao.com/ csusm clothing

WebCryptands III.1 Introduction Like crown ethers, cryptands were designed and synthesized as binding receptors of smaller molecular substrates. A simple definition of a cryptand is a bicyclic (or polycyclic) ligand.1 This definition was derived from Lehn's observations of the behavior of cryptands with alkali metals.
