recommendations! Published in 2017 at "Inorganica Chimica Acta"

DOI: 10.1016/j.ica.2017.04.033

Abstract: Abstract The high pressure liquid chromatography (HPLC) retention behavior of fullerenes and metallofullerenes provides a convenient system for studying the intermolecular interactions between conjugated spheroidal π systems and stationary chromatographic phases. Previous studies have established… read more here.
