Interaction of organonitriles with electron rich calix[4]arene derivatives on gold substrates
We synthesized 25,26,27,28- tetrakis( mercaptobuthoxy)- 5,11,17,23-[ 2,20- thioxy( ophenylene) thioxy- piperidino] calix[ 4] arene [ 1], 25,26,27,28- tetrakis( mercaptobuthoxy)5,11,17,23-[ 2,20- thioxy( o- phenylene) thioxy- amino] calix[ 4] arene [ 2] and 25,26,27,28tetrakis( mercaptobuthoxy)- 5,11,17,23-[ 2,20- thioxy( o- phenylene) thioxy- aminopyrene] calix[ 4] arene [ 3] containing four alkyl thiol linkages, which allow the calix[ 4] arene to attach on the gold surface. We observed the binding of calix[ 4] arene derivatives and aromatic molecules with surface plasmon resonance and confirmed complexation of aromatic nitriles on calix[ 4] arene derivatives with FT- IR peak.
