Leyton, Patricio; Domingo, C.; Sánchez Cortés, S.; Campos Vallette, Marcelo; Díaz, G. F.; García Ramos, J. V. (2007)A vibrational study of the calix[4]arene derivative 25,26,27,28-tetracarboethoxy-p-tert-butylcalix[4]arene (TCEC) is accomplished in this work. This characterization implies a study of its adsorption on metal (Cu and Ag) ...
