DFT Study of Hydrogen Bonding on Calix[8]arene as Nanostructure Compound

An azobenzene bridge was introduced into the lower (or smaller) rim of p-tert-butylcalix[8]arene to form 1,5- singly bridged calix[8]arene derivatives, respectively. Bridged calix[8]arene of conformationally rigid were isolated. The stability of the two structures of bridged calix[8]arenes have been compared.The study of organic structure to form nanoporous structures is a well known in chemistry phenomena to finding crystal structure of calix[8]arene as supramolecular chemistry. The effect of hydrogen bonding on calix[8]arene was reported at Density Functional Theory by Gaussian 98 of program package. The self assembled nanotubes in solid state through network hydrogen bonds between the chains of this structure were investigated.
