Abstract
We synthesized 25,26,27,28-tetrakis(mercaptobuthoxy)-5,11,17,23-[2,2′-thioxy(o-phenylene)thioxy-piperidino]calix[Citation4]arene [Citation1], 25,26,27,28-tetrakis(mercaptobuthoxy)-5,11,17,23-[2,2′-thioxy(o-phenylene)thioxy-amino]calix[Citation4]arene [Citation2] and 25,26,27,28-tetrakis(mercaptobuthoxy)-5,11,17,23-[2,2′-thioxy(o-phenylene)thioxy-aminopyrene] calix[Citation4]arene [Citation3] containing four alkyl thiol linkages, which allow the calix[Citation4]arene to attach on the gold surface. We observed the binding of calix[Citation4]arene derivatives and aromatic molecules with surface plasmon resonance and confirmed complexation of aromatic nitriles on calix[Citation4]arene derivatives with FT-IR peak.
