Synthesis, solid state structures and interfacial properties of new para-phosphonato-O-alkoxy-calix[8]arene derivatives
Abstract
The synthesis of six para-phosphonato-alkoxy-calix[8]arene derivatives are described. Here, a total of 24 intermediates have been isolated, and X-ray structures of the octabromo-octamethoxy-calix[8]arene and octabromo-octabutoxy-calix[8]arene have been resolved. The interfacial properties of the para-phosphonato-alkoxy-calix[8]arene derivatives and their di-iso-propoxy-protected analogues have been determined.
