Calix-arene silver nanoparticles interactions with surfactants are charge, size and critical micellar concentration dependent

Chem Commun (Camb). 2012 Oct 4;48(76):9483-5. doi: 10.1039/c2cc34670b.

Abstract

The interactions of silver nanoparticles capped by various calix[n]arenes bearing sulphonate groups at the para and/or phenolic faces with cationic, neutral and anionic surfactants have been studied. Changes in the plasmonic absorption show that only the calix[4]arene derivatives sulphonated at the para-position interact and then only with cationic surfactants. The interactions follow the CMC values of the surfactants either as simple molecules or mixed micelles.
