Sulfonatocalix[8]arene as a potential reaction cavity: photo- and electro-active dicationic guests arrest conformational equilibrium.

Smaller members of water-soluble sulfonated calixarenes have been extensively explored in the context of host-guest complexation, supramolecular chemistry, and potential sensors. However, larger members especially eight-membered calixarene (CA[8]) has received much less attention because of its floppy nature and tendency to exist as a mixture of… (More)
