Synthesis and Complexing Properties of Novel Tetraphosphonate-Calix[4] Resorcinarenes

Abstract We recently reported the synthesis of phosphorylated cavitands and their high affinity for cationic species 1. We have thus synthesized and explored the properties of novel phosphacavitands containing four long R chain substituents at their lower rim. The amphiphilic molecule 2 could be inwoduced into a micelle. The compounds 3 and 4 could be used respectively as a cation carrier into Supported Liquid Membrane and as a sensor into a Self-Assembled Monolayer on gold.2, 3
