Abstract
Oxygen atom bridged calixarene derivatives called oxacalixarenes were synthesized from bisphenol A and cyanuric chloride by aromatic nucleophilic substitution through addition elimination mechanism. All the synthesized oxacalixarenes exhibit strong absorbance band between 225 and 286 nm due to the presence of triazine and phenoxy units. The oxacalixarenes 7 and 10 show strong fluorescence emission and higher λem values than all other oxacalixarenes due to the presence of rigid aromatic spacer units such as binol and biphenyl. All the oxacalixarenes exhibit quasi-reversible behaviour and potential shift observed in cyclic voltammetry.
