Abstract: In this study, tungstic acid immobilized on polycalix[4]resorcinarene, PC4RA@SiPr–OWO3H, as a mesoporous acidic solid catalyst was synthesized and investigated for its catalytic activity. Polycalix[4]resorcinarene was prepared via a reaction between formaldehyde and calix[4]resorcinarene, and then… read more here.
